Conditions with this feature

Eichsfeld type congenital muscular dystrophy
MedGen UID:
98047
Concept ID:
C0410180
Disease or Syndrome
Rigid spine muscular dystrophy (RSMD) is a form of congenital muscular dystrophy. Disorders in this group cause muscle weakness and wasting (atrophy) beginning very early in life. In particular, RSMD involves weakness of the muscles of the torso and neck (axial muscles). Other characteristic features include spine stiffness and serious breathing problems.\n\nIn RSMD, muscle weakness is often apparent at birth or within the first few months of life. Affected infants can have poor head control and weak muscle tone (hypotonia), which may delay the development of motor skills such as crawling or walking. Over time, muscles surrounding the spine atrophy, and the joints of the spine develop deformities called contractures that restrict movement. The neck and back become stiff and rigid, and affected children have limited ability to move their heads up and down or side to side. Affected children eventually develop an abnormal curvature of the spine (scoliosis). In some people with RSMD, muscles in the inner thighs also atrophy, although it does not impair the ability to walk.\n\nA characteristic feature of RSMD is breathing difficulty (respiratory insufficiency) due to restricted movement of the torso and weakness of the diaphragm, which is the muscle that separates the abdomen from the chest cavity. The breathing problems, which tend to occur only at night, can be life-threatening. Many affected individuals require a machine to help them breathe (mechanical ventilation) during sleep.\n\nThe combination of features characteristic of RSMD, particularly axial muscle weakness, spine rigidity, and respiratory insufficiency, is sometimes referred to as rigid spine syndrome. While these features occur on their own in RSMD, they can also occur along with additional signs and symptoms in other muscle disorders. The features of rigid spine syndrome typically appear at a younger age in people with RSMD than in those with other muscle disorders.

Disease or Syndrome
Bethlem myopathy-1 (BTHLM1) is a congenital muscular dystrophy characterized by distal joint laxity and a combination of distal and proximal joint contractures. The age at onset is highly variable, ranging from infancy to adulthood. Disease progression is slow and ambulation is usually retained into adulthood (summary by Butterfield et al., 2013). Genetic Heterogeneity of Bethlem Myopathy See Bethlem myopathy-1B (BTHLM1B; 620725), caused by mutation in the COL6A2 gene (120240) on chromosome 21q22; Bethlem myopathy-1C (620726), caused by mutation the COL6A3 gene (120250) on chromosome 2q37; and Bethlem myopathy-2 (BTHLM2; 616471), caused by mutation in the COL12A1 gene (120320) on chromosome 6q13-q14.
Congenital multicore myopathy with external ophthalmoplegia
MedGen UID:
340597
Concept ID:
C1850674
Disease or Syndrome
Congenital myopathy-1B (CMYO1B) is an autosomal recessive disorder of skeletal muscle characterized by severe hypotonia and generalized muscle weakness apparent soon after birth or in early childhood with delayed motor development, generalized muscle weakness and atrophy, and difficulty walking or running. Affected individuals show proximal muscle weakness with axial and shoulder girdle involvement, external ophthalmoplegia, and bulbar weakness, often resulting in feeding difficulties and respiratory insufficiency. Orthopedic complications such as joint laxity, distal contractures, hip dislocation, cleft palate, and scoliosis are commonly observed. Serum creatine kinase is normal. The phenotype is variable in severity (Jungbluth et al., 2005; Bharucha-Goebel et al., 2013). Some patients show symptoms in utero, including reduced fetal movements, polyhydramnios, and intrauterine growth restriction. The most severely affected patients present in utero with fetal akinesia, arthrogryposis, and lung hypoplasia resulting in fetal or perinatal death (McKie et al., 2014). Skeletal muscle biopsy of patients with recessive RYR1 mutations can show variable features, including multiminicores (Ferreiro and Fardeau, 2002), central cores (Jungbluth et al., 2002), congenital fiber-type disproportion (CFTD) (Monnier et al., 2009), and centronuclear myopathy (Wilmshurst et al., 2010). For a discussion of genetic heterogeneity of congenital myopathy, see CMYO1A (117000).
Congenital myasthenic syndrome 10
MedGen UID:
376880
Concept ID:
C1850792
Disease or Syndrome
Congenital myasthenic syndromes (CMS) are a group of inherited disorders affecting the neuromuscular junction (NMJ). Patients present clinically with onset of variable muscle weakness between infancy and adulthood. These disorders have been classified according to the location of the defect: presynaptic, synaptic, and postsynaptic. CMS10 is an autosomal recessive CMS resulting from a postsynaptic defect affecting endplate maintenance of the NMJ. Patients present with limb-girdle weakness in the first decade. Treatment with ephedrine or salbutamol may be beneficial; cholinesterase inhibitors should be avoided (summary by Engel et al., 2015). For a discussion of genetic heterogeneity of CMS, see CMS1A (601462).
Congenital muscular dystrophy due to LMNA mutation
MedGen UID:
413043
Concept ID:
C2750785
Disease or Syndrome
LMNA-related congenital muscular dystrophy (L-CMD) is a condition that primarily affects muscles used for movement (skeletal muscles). It is part of a group of genetic conditions called congenital muscular dystrophies, which cause weak muscle tone (hypotonia) and muscle wasting (atrophy) beginning very early in life.\n\nIn people with L-CMD, muscle weakness becomes apparent in infancy or early childhood and can worsen quickly. The most severely affected infants develop few motor skills, and they are never able to hold up their heads, roll over, or sit. Less severely affected children may learn to sit, stand, and walk before muscle weakness becomes apparent. First the neck muscles weaken, causing the head to fall forward (dropped-head syndrome). As other skeletal muscles become weaker, these children may ultimately lose the ability to sit, stand, and walk unassisted.\n\nOther features of L-CMD often include spinal rigidity and abnormal curvature of the spine (scoliosis and lordosis); joint deformities (contractures) that restrict movement, particularly in the hips and legs; and an inward-turning foot. People with L-CMD also have an increased risk of heart rhythm abnormalities (arrhythmias).\n\nOver time, muscle weakness causes most infants and children with L-CMD to have trouble eating and breathing. The breathing problems result from restrictive respiratory insufficiency, which occurs when muscles in the chest are weakened and the ribcage becomes increasingly rigid. This problem can be life-threatening, and many affected children require support with a machine to help them breathe (mechanical ventilation).
Myofibrillar myopathy 6
MedGen UID:
414119
Concept ID:
C2751831
Disease or Syndrome
Myofibrillar myopathy-6 is an autosomal dominant severe neuromuscular disorder characterized by onset in the first decade of rapidly progressive generalized and proximal muscle weakness, respiratory insufficiency, cardiomyopathy, and skeletal deformities related to muscle weakness. Muscle biopsy shows fiber-type grouping, disruption of the Z lines, and filamentous inclusions, and sural nerve biopsy shows a neuropathy, often with giant axonal neurons. Most patients are severely affected by the second decade and need cardiac transplant, ventilation, and/or a wheelchair (summary by Jaffer et al., 2012). For a phenotypic description and a discussion of genetic heterogeneity of myofibrillar myopathy (MFM), see MFM1 (601419).
Congenital myopathy 10b, mild variant
MedGen UID:
762102
Concept ID:
C3541476
Disease or Syndrome
Congenital myopathy-10B (CMYO10B) is an autosomal recessive skeletal muscle disorder characterized by infantile- or childhood-onset myopathy, areflexia, dysphagia, and respiratory distress that usually requires nocturnal ventilation. Other common features include facial and neck muscle weakness, feeding difficulties, contractures, scoliosis, high-arched palate, hyporeflexia, and difficulties walking. The disorder is slowly progressive and most patients follow a chronic course. Muscle biopsy shows variable findings, including type 1 fiber predominance, minicore lesions, and myofibrillar disorganization (Boyden et al., 2012; Harris et al., 2018). Patients with missense mutations affecting conserved cysteine residues in the EGF-like domain show the mild variant phenotype (CMYO10B) with later onset of respiratory failure and minicores on muscle biopsy, whereas patients with more damaging mutations, including nonsense or frameshift null mutations, show the severe variant phenotype (CMYO10A) (Croci et al., 2022).

Congenital myopathy 18
MedGen UID:
1840919
Concept ID:
C5830283
Disease or Syndrome
Congenital myopathy-18 (CMYO18) is a disorder of the skeletal muscle characterized by the onset of symptoms of muscle weakness in early childhood, including in utero and infancy. There is clinical heterogeneity in the manifestations and severity, ranging from fetal akinesia sequence causing early death to onset of symptoms in adulthood. Most affected individuals show delayed motor development with generalized hypotonia and progressive axial and limb muscle weakness beginning soon after birth or in infancy. Additional features may include swallowing difficulties, external ophthalmoplegia, ptosis, high-arched palate, and respiratory insufficiency, which can lead to death in severe cases. Muscle biopsy shows variable morphologic abnormalities, including alveolar changes in the intermyofibrillar network, fiber size variability, focal disorganization, internal nuclei, and dilated sarcoplasmic reticulum and T-tubules. The disorder results from a defect in excitation-contraction coupling in skeletal muscle (Schartner et al., 2017; Ravenscroft et al., 2021; Mauri et al., 2021; Yis et al., 2019). For a discussion of genetic heterogeneity of congenital myopathy, see CMYO1A (117000).

Concept ID:
C5830501
Disease or Syndrome
Severe fetal congenital myopathy-22B (CMYO22B) is an autosomal recessive muscle disorder characterized by in utero onset of severe muscle weakness manifest as fetal akinesia. The pregnancies are often complicated by polyhydramnios, and affected individuals develop fetal hydrops with pulmonary hypoplasia, severe joint contractures, and generalized muscle hypoplasia. Those who are born have respiratory failure resulting in death. Dysmorphic facial features may be present. The features in these patients overlap with fetal akinesia deformation sequence (FADS; see 208150) and lethal congenital contractures syndrome (LCCS; see 253310) (Zaharieva et al., 2016). For a discussion of genetic heterogeneity of congenital myopathy, see CMYO1A (117000).
Muscular dystrophy, limb-girdle, autosomal recessive 28
MedGen UID:
1841154
Concept ID:
C5830518
Disease or Syndrome
Autosomal recessive limb-girdle muscular dystrophy-28 (LGMDR28) is characterized by progressive muscle weakness affecting the proximal and axial muscles of the upper and lower limbs. The age at onset is highly variable, usually in the first decade, although onset in the fourth decade has also been reported. The disorder can be rapidly progressive or show a slower course. Most patients have limited ambulation or become wheelchair-bound within a few decades, and respiratory insufficiency commonly occurs. Laboratory studies show increased serum creatine kinase and elevated fasting blood glucose levels, although cholesterol is normal. EMG shows a myopathic pattern; muscle biopsy is generally unremarkable, but can show nonspecific myopathic or dystrophic features (Yogev et al., 2023; Morales-Rosado et al., 2023). For a discussion of genetic heterogeneity of autosomal recessive limb-girdle muscular dystrophy, see LGMDR1 (253600).
