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]

For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individual(s) with osteogenesis imperfecta (PMID: 27362741). ClinVar contains an entry for this variant (Variation ID: 222952). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Met326Trpfs*39) 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). -
