X-linked intellectual disability-cubitus valgus-dysmorphism syndrome

MedGen UID:
1801270
•Concept ID:
C5677056
•
Disease or Syndrome
Synonym: CUBITUS VALGUS WITH IMPAIRED INTELLECTUAL DEVELOPMENT AND UNUSUAL FACIES
Modes of inheritance:
X-linked recessive inheritance
MedGen UID:
375779
•Concept ID:
C1845977
•
Finding
Source: Orphanet
A mode of inheritance that is observed for recessive traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele.

Monarch Initiative: MONDO:0010332
OMIM®: 300471
Orphanet: ORPHA85280

Definition

X-linked intellectual disability-cubitus valgus-dysmorphism syndrome is characterised by moderate intellectual deficit, marked <i>cubitus valgus</i>, mild microcephaly, a short philtrum, deep-set eyes, downslanting palpebral fissures and multiple nevi. Less than ten individuals have been described so far. Transmission is thought to be X-linked recessive. [from ORDO]
