Camptodactyly-tall stature-scoliosis-hearing loss syndrome(CATSHLS)

MedGen UID:
355844
Concept ID:
C1864852
Disease or Syndrome
Synonym: Camptodactyly, tall stature, and hearing loss syndrome
SNOMED CT: CATSHL (camptodactyly, tall stature, scoliosis, hearing loss) syndrome (720601000); Camptodactyly and tall stature with scoliosis and hearing loss syndrome (720601000)
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).
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
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 heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

This syndrome has characteristics of camptodactyly, tall stature, scoliosis, and hearing loss (CATSHL). It has been described in around 30 individuals from seven generations of the same family. The syndrome is caused by a missense mutation in the FGFR3 gene, leading to a partial loss of function of the encoded protein, which is a negative regulator of bone growth. [from SNOMEDCT_US]

Intellectual disability
MedGen UID:
811461
Concept ID:
C3714756
Mental or Behavioral Dysfunction
Intellectual disability, previously referred to as mental retardation, is characterized by subnormal intellectual functioning that occurs during the developmental period. It is defined by an IQ score below 70.
Osteochondroma
MedGen UID:
10496
Concept ID:
C0029423
Anatomical Abnormality
A cartilage capped bony outgrowth of a long bone. Osteochondroma arises on the external surface of bone containing a marrow cavity that is continuous with that of the underlying bone.
Scoliosis
MedGen UID:
11348
Concept ID:
C0036439
Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
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.
Increased vertebral height
MedGen UID:
400628
Concept ID:
C1864853
Finding
Increased top to bottom height of vertebral bodies.
Pectus excavatum

Camptodactyly of toe
MedGen UID:
867404
Concept ID:
C4021774
Anatomical Abnormality
Camptodactyly is a painless flexion contracture of the proximal interphalangeal (PIP) joint that is usually gradually progressive. This term refers to camptodactyly of one or more toes.

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).
