Locus HSAN-VIII PRDM12

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 9q34¹.

Prevalence

Expansions found in 2 families from Pakistan and Saudi Arabia². All PRDM12 disease mutations < 1/1,000,000

Age of Onset

0 (birth)

Locus

hg19 chr9:133556992-133557028

hg38 chr9:130681605-130681641

t2t chr9:142886568-142886595

Details

Pathogenic expansion found in 2 families, from whom pathogenic range (18-19) is inferred². Benign range (7-14) inferred from Human Gene Mutation Database³.

Mechanism

LoF

Mutations abrogate the histone-modifying potential of PRDM12, consistent with a loss of function mechanism⁴.
