Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).

Definition

Syndrome with characteristics of highly arched palate with bifid tongue and bilateral supernumerary lower canines, hamartomatous tongue, multiple frenula, hypertelorism, telecanthus, strabismus, broad and/or bifid nasal tip, short stature, bifid hallux, forked metatarsal, poly and syndactyly, mild intellectual deficit and specific retinal abnormalities (bilateral optic disc coloboma and retinal dysplasia with partial detachment).

Clinical features

From HPO
Hamartoma
MedGen UID:
6713
Concept ID:
C0018552
Neoplastic Process
A disordered proliferation of mature tissues that is native to the site of origin, e.g., exostoses, nevi and soft tissue hamartomas. Although most hamartomas are benign, some histologic subtypes, e.g., neuromuscular hamartoma, may proliferate aggressively such as mesenchymal cystic hamartoma, Sclerosing epithelial hamartoma, Sclerosing metanephric hamartoma.
Hand polydactyly
MedGen UID:
510636
Concept ID:
C0158733
Congenital Abnormality
A kind of polydactyly characterized by the presence of a supernumerary finger or fingers.
Toe syndactyly
MedGen UID:
75581
Concept ID:
C0265660
Congenital Abnormality
Webbing or fusion of the toes, involving soft parts only or including bone structure. Bony fusions are referred to as "bony" Syndactyly if the fusion occurs in a radio-ulnar axis. Fusions of bones of the toes in a proximo-distal axis are referred to as "Symphalangism".
Short tibia
MedGen UID:
338005
Concept ID:
C1850259
Finding
Underdevelopment (reduced size) of the tibia.
Short stature
MedGen UID:
87607
Concept ID:
C0349588
Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Global developmental delay
MedGen UID:
107838
Concept ID:
C0557874
Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Brain atrophy
MedGen UID:
1643639
Concept ID:
C4551584
Disease or Syndrome
Partial or complete wasting (loss) of brain tissue that was once present.
Camptodactyly
MedGen UID:
195780
Concept ID:
C0685409
Congenital Abnormality
The distal interphalangeal joint and/or the proximal interphalangeal joint of the fingers or toes cannot be extended to 180 degrees by either active or passive extension.
Microcephaly
MedGen UID:
1644158
Concept ID:
C4551563
Finding
Head circumference below 2 standard deviations below the mean for age and gender.
Hypoplasia of the epiglottis
MedGen UID:
235600
Concept ID:
C1396772
Congenital Abnormality
Hypoplasia of the epiglottis.
Recurrent aspiration pneumonia
MedGen UID:
152887
Concept ID:
C0747651
Disease or Syndrome
Increased susceptibility to aspiration pneumonia, defined as pneumonia due to breathing in foreign material, as manifested by a medical history of repeated episodes of aspiration pneumonia.
High palate
MedGen UID:
66814
Concept ID:
C0240635
Congenital Abnormality
Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective).
Abnormality of the dentition
MedGen UID:
78084
Concept ID:
C0262444
Finding
Any abnormality of the teeth.
Telecanthus
MedGen UID:
140836
Concept ID:
C0423113
Finding
Distance between the inner canthi more than two standard deviations above the mean (objective); or, apparently increased distance between the inner canthi.
Bifid nasal tip
MedGen UID:
140870
Concept ID:
C0426428
Finding
A splitting of the nasal tip. Visually assessable vertical indentation, cleft, or depression of the nasal tip.
Broad nasal tip
MedGen UID:
98424
Concept ID:
C0426429
Finding
Increase in width of the nasal tip.
Median cleft upper lip
MedGen UID:
342454
Concept ID:
C1850256
Congenital Abnormality
A type of cleft lip presenting as a midline (median) gap in the upper lip.
Cleft palate
MedGen UID:
756015
Concept ID:
C2981150
Congenital Abnormality
Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate).
Accessory oral frenulum
MedGen UID:
867439
Concept ID:
C4021814
Congenital Abnormality
Extra fold of tissue extending from the alveolar ridge to the inner surface of the upper or lower lip.
Milia
MedGen UID:
87528
Concept ID:
C0345996
Anatomical Abnormality
Presence of multiple small cysts containing keratin (skin protein) and presenting as tiny pearly-white bumps just under the surface of the skin.
Hypertelorism
MedGen UID:
9373
Concept ID:
C0020534
Finding
Although hypertelorism means an excessive distance between any paired organs (e.g., the nipples), the use of the word has come to be confined to ocular hypertelorism. Hypertelorism occurs as an isolated feature and is also a feature of many syndromes, e.g., Opitz G syndrome (see 300000), Greig cephalopolysyndactyly (175700), and Noonan syndrome (163950) (summary by Cohen et al., 1995).
Strabismus
MedGen UID:
21337
Concept ID:
C0038379
Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.
Retinal coloboma
MedGen UID:
761889
Concept ID:
C3540764
Disease or Syndrome
A notch or cleft of the retina.
