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.
Features include always present findings: Impaired temperature sensation and Pain insensitivity; and very common findings: Recurrent skin infections. 15 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Brain and nerves | 2 | Hyporeflexia, Intellectual disability |
PRDM12 function has not been fully characterized.
Congenital insensitivity to pain-hypohidrosis syndrome is associated with mutations in the PRDM12 gene on chromosome 9.
Genetic testing for PRDM12 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 2 always present features, 1 very common feature, 4 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for congenital insensitivity to pain-hypohidrosis syndrome.
152 publications have been identified in PubMed for congenital insensitivity to pain-hypohidrosis syndrome. Kisho has analyzed 27 by research type. Research spans Case Report / Case Series (52%), Review / Meta-Analysis (33%), and Basic Science / Preclinical (7%).
