Congenital insensitivity to pain-hypohidrosis syndrome Uncertain:1
In summary, this variant is a rare in-frame duplication that has been shown to affect protein function. While it is absent from the population and reported in affected individuals, the available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies have shown that this polyalanine expansion variant forms aggregates and reduces PRDM12 expression in vitro (PMID: 26005867). This variant has been reported to segregate with congenital insensitivity to pain in a single family (PMID: 26005867). This variant is not present in population databases (ExAC no frequency). This sequence change inserts 21 nucleotides in exon 5 of the PRDM12 mRNA (c.1056_1076dup). This leads to the insertion of 7 alanine amino acid residuer in the PRDM12 protein (p.Ala353_Ala359dup) but otherwise preserves the integrity of the reading frame. -
