Summaries for Neuropathy, Hereditary Sensory and Autonomic, Type Viii

UniProtKB/Swiss-Prot : 75 Neuropathy, hereditary sensory and autonomic, 8: A form of hereditary sensory and autonomic neuropathy, a genetically and clinically heterogeneous group of disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and by sensory and/or autonomic abnormalities. HSAN8 patients manifest congenital insensitivity to pain resulting in ulceration to the fingers, tongue, lips, and other distal appendages. Some patients may also have decreased sweating and tear production.

MalaCards based summary : Neuropathy, Hereditary Sensory and Autonomic, Type Viii, also known as hsan8, is related to hereditary sensory neuropathy and autonomic neuropathy. An important gene associated with Neuropathy, Hereditary Sensory and Autonomic, Type Viii is PRDM12 (PR/SET Domain 12). Affiliated tissues include tongue, skin and eye, and related phenotypes are hypohidrosis and recurrent infections

Disease Ontology : 12 A hereditary sensory neuropathy characterized by congenital insensitivity to pain and decreased sweating and tear production that has material basis in homozygous mutation in the PRDM12 gene on chromosome 9q34.

OMIM : 57 Hereditary sensory and autonomic neuropathy type VIII is an autosomal recessive neurologic disorder characterized by congenital insensitivity to pain resulting in ulceration to the fingers, tongue, lips, and other distal appendages. Affected individuals may also have decreased sweating and tear production (summary by Chen et al., 2015). For a discussion of genetic heterogeneity of hereditary sensory and autonomic neuropathy, see HSAN1A (162400). (616488)
