Dystonia 24(DYT24)

MedGen UID:
767288
•Concept ID:
C3554374
•
Disease or Syndrome
Synonyms: DYT-ANO3; DYT24
SNOMED CT: Dystonia 24 (783179009); Cranio-cervical dystonia with laryngeal and upper limb involvement (783179009); DYT24 - dystonia 24 (783179009)
Modes of inheritance:
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.
Autosomal dominant inheritance (Orphanet)
 
Gene (location): ANO3 (11p14.3-14.2)
 
Monarch Initiative: MONDO:0014019

Definition

Dystonia-24 is an autosomal dominant form of focal dystonia affecting the neck, laryngeal muscles, and muscles of the upper limbs (summary by Charlesworth et al., 2012). [from OMIM]

Clinical features

Torticollis
MedGen UID:
11859
•Concept ID:
C0040485
•
Sign or Symptom
Torticollis is a twisted neck as a result of shortening of sternocleidomastoid muscle. This short and fibrotic muscle pulls the head laterally and rotates the chin and face to the opposite end. Facial asymmetry may be a manifestation (summary by Engin et al., 1997).
