Genes affected

FKBP10 (HGNC:18169): (FKBP prolyl isomerase 10) The protein encoded by this gene belongs to the FKBP-type peptidyl-prolyl cis/trans isomerase (PPIase) family. This protein localizes to the endoplasmic reticulum and acts as a molecular chaperone. Alternatively spliced variants encoding different isoforms have been reported, but their biological validity has not been determined.[provided by RefSeq, Nov 2009]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 8 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-41813039-TC-T is Pathogenic according to our data. Variant chr17-41813039-TC-T is described in ClinVar as [Pathogenic]. Clinvar id is 2031705.Status of the report is criteria_provided_single_submitter, 1 stars.

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with FKBP10-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ala4Argfs*155) in the FKBP10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FKBP10 are known to be pathogenic (PMID: 22689593, 22949511). -
