Carey-Fineman-Ziter syndrome 2(CFZS2)

MedGen UID:
1800921
Concept ID:
C5677012
Disease or Syndrome
Synonym: CFZS2
 
Gene (location): MYMX (6p21.1)
 
Monarch Initiative: MONDO:0100292
OMIM®: 619941

Definition

Carey-Fineman-Ziter syndrome-2 (CFZS2) is an autosomal recessive disorder characterized by weakness of the facial musculature, hypomimic facies, increased overbite, micrognathia, and facial dysmorphism. Other features may include failure to thrive, axial hypotonia, and progressive scoliosis (Ramirez-Martinez et al., 2022). For a discussion of genetic heterogeneity of Carey-Fineman-Ziter syndrome, see CFZS1 (254940). [from OMIM]

Clinical features

Concept ID:
C0728829
Congenital Abnormality
An increase in height of the medial longitudinal arch of the foot that does not flatten on weight bearing (i.e., a distinctly hollow form of the sole of the foot when it is bearing weight).
Pes valgus
MedGen UID:
299028
Concept ID:
C1578482
Anatomical Abnormality
An outward deviation of the foot at the talocalcaneal or subtalar joint.
Failure to thrive
MedGen UID:
746019
Concept ID:
C2315100
Disease or Syndrome
Failure to thrive (FTT) refers to a child whose physical growth is substantially below the norm.
Low-set ears
MedGen UID:
65980
Concept ID:
C0239234
Congenital Abnormality
Upper insertion of the ear to the scalp below an imaginary horizontal line drawn between the inner canthi of the eye and extending posteriorly to the ear.
Posteriorly rotated ears
MedGen UID:
96566
Concept ID:
C0431478
Congenital Abnormality
A type of abnormal location of the ears in which the position of the ears is characterized by posterior rotation (the superior part of the ears is rotated towards the back of the head, and the inferior part of the ears towards the front).
Protruding ear
MedGen UID:
343309
Concept ID:
C1855285
Finding
Angle formed by the plane of the ear and the mastoid bone greater than the 97th centile for age (objective); or, outer edge of the helix more than 2 cm from the mastoid at the point of maximum distance (objective).
Micrognathia
MedGen UID:
44428
Concept ID:
C0025990
Congenital Abnormality
Developmental hypoplasia of the mandible.
Scoliosis
MedGen UID:
11348
Concept ID:
C0036439
Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
Muscle weakness
MedGen UID:
57735
Concept ID:
C0151786
Finding
Reduced strength of muscles.
Weakness of facial musculature
MedGen UID:
98103
Concept ID:
C0427055
Disease or Syndrome
Reduced strength of one or more muscles innervated by the facial nerve (the seventh cranial nerve).
Axial muscle weakness
MedGen UID:
334472
Concept ID:
C1843697
Finding
Reduced strength of the axial musculature (i.e., of the muscles of the head and neck, spine, and ribs).
Abnormal skeletal muscle morphology
MedGen UID:
868776
Concept ID:
C4023181
Anatomical Abnormality
A structural abnormality of a skeletal muscle.
Hypernasal speech
MedGen UID:
99115
Concept ID:
C0454555
Finding
A type of speech characterized by the presence of an abnormally increased nasal airflow during speech associated with structural abnormality of the nasal passages.
Dental crowding
MedGen UID:
11850
Concept ID:
C0040433
Finding
Changes in alignment of teeth in the dental arch
Velopharyngeal insufficiency
MedGen UID:
52992
Concept ID:
C0042454
Finding
Inability of velopharyngeal sphincter to sufficiently separate the nasal cavity from the oral cavity during speech.
Increased overbite
MedGen UID:
539656
Concept ID:
C0266063
Disease or Syndrome
Maxillary teeth cover the mandibular teeth when biting to an increased degree. The feature is defined as a vertical overlap of the maxillary incisors over the mandibular incisors that exceeds 2 mm.
Hypomimic face
MedGen UID:
208827
Concept ID:
C0813217
Finding
A reduced degree of motion of the muscles beneath the skin of the face, often associated with reduced facial crease formation.
Underdeveloped nasal alae
MedGen UID:
322332
Concept ID:
C1834055
Congenital Abnormality
Thinned, deficient, or excessively arched ala nasi.
High, narrow palate
MedGen UID:
324787
Concept ID:
C1837404
Finding
The presence of a high and narrow palate.
Anteverted nares
MedGen UID:
326648
Concept ID:
C1840077
Finding
Anteriorly-facing nostrils viewed with the head in the Frankfurt horizontal and the eyes of the observer level with the eyes of the subject. This gives the appearance of an upturned nose (upturned nasal tip).
Long philtrum
MedGen UID:
351278
