MedGen UID:
816212
•Concept ID:
C3809882
•
Disease or Syndrome
Synonyms: HSAN VII; Neuropathy, hereditary sensory and autonomic, type VII

Modes of inheritance:
Autosomal dominant inheritance

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

Hereditary sensory and autonomic neuropathy type VII (HSAN7) is characterized by congenital absence of pain sensation resulting in recurrent injuries and self-inflicted wounds. Severe pruritis, intestinal dysmotility, and hyperhydrosis may be present (Woods et al., 2015; Salvatierra et al., 2018). For a discussion of genetic heterogeneity of hereditary sensory and autonomic neuropathy, see HSAN1 (162400). [from OMIM]
