Short ulna-dysmorphism-hypotonia-intellectual disability syndrome(MRT35)

MedGen UID:
767523
Concept ID:
C3554609
Mental or Behavioral Dysfunction
Synonym: MRT35
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

Short ulna-dysmorphism-hypotonia-intellectual disability syndrome is a rare, genetic, multiple congenital anomalies/dysmorphic syndrome characterized by mild to severe global development delay, severe intellectual disability, mild hypotonia, a short ulna, hirsutism of the face and extremities, minimal scoliosis, and facial dysmorphism, notably a tall broad forehead, synophrys, hypertelorism, malar hypoplasia, broad nose with thick alae nasi, low-set, small ears, long philtrum, thin upper lip and everted lower lip vermilion. [from ORDO]

MedGen UID:
355352

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).
