Genes affected

PRDM12 (HGNC:13997): (PR/SET domain 12) This gene encodes a transcriptional regulator of sensory neuronal specification that plays a critical role in pain perception. The encoded protein contains an N-terminal PRDI-BF1 and RIZ homology (PR) domain, a SET domain, and three C-terminal C2H2 zinc finger DNA-binding domains. Naturally occurring mutations in this gene are associated with congenital insensitivity to pain (CIP), and hereditary sensory and autonomic neuropathies (HSAN's) affecting peripheral sensory and autonomic neurons. Deregulation of this gene is associated with solid cancers and hematological malignancies including chronic myeloid leukaemia. [provided by RefSeq, Mar 2017]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.00211972).
• BP6: Variant 9-130681560-C-A is Benign according to our data. Variant chr9-130681560-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 475818.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-130681560-C-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00128 (189/148014) while in subpopulation NFE AF= 0.00206 (137/66520). AF 95% confidence interval is 0.00178. There are 0 homozygotes in gnomad4. There are 78 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
