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

DYT-GNAL caused by a heterozygous GNAL pathogenic variant has been reported in more than 60 individuals to date. It is characterized by adult-onset isolated dystonia (i.e., no neurologic abnormalities other than tremor are evident on neurologic examination). The dystonia is most commonly focal and segmental, and rarely generalized. Dystonia is typically cervical in onset and commonly progresses to the cranial region (oromandibular/jaw, larynx, eyelids) and/or to one arm. Tremor reported in DYT-GNAL may be dystonic (i.e., occurring in a body part that shows at least minimal signs of dystonia) and may precede or follow the onset of dystonia. Intra- and interfamilial variability is considerable. DYT-GNAL caused by biallelic GNAL pathogenic variants, reported to date in two sibs from a consanguineous family, is characterized by mild intellectual disability and childhood-onset hypertonia that progresses to generalized dystonia. [from GeneReviews]

Additional description

From OMIM
Dystonia-25 is an autosomal dominant neurologic disorder characterized by adult onset of focal dystonia, usually involving the neck. The dystonia most often progresses to involve other regions, particularly the face and laryngeal muscles, and less commonly the trunk and limbs (summary by Fuchs et al., 2013).  http://www.omim.org/entry/615073

Clinical features

From HPO
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).

Limb dystonia
MedGen UID:
152944
•Concept ID:
C0751093
•
Sign or Symptom
A type of dystonia (abnormally increased muscular tone causing fixed abnormal postures) that affects muscles of the limbs.

Laryngeal dystonia
MedGen UID:
409603
•Concept ID:
C1963946
•
Disease or Syndrome
A form of focal dystonia that affects the vocal cords, associated with involuntary contractions of the vocal cords causing interruptions of speech and affecting the voice quality and often leading to patterned, repeated breaks in speech.
