Bruck syndrome 1 Pathogenic:2

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.001%). Protein truncation variants are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.90; 3Cnet: 0.76). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with FKBP10- related disorder (ClinVar ID: VCV000030634 / PMID: 20839288). The variant has been reported to be in trans with a pathogenic variant as compound heterozygous in at least one similarly affected unrelated individual (PMID: 20839288). The variant has been reported to co-segregate with the disease in at least 3 similarly affected relatives/individuals in the same family or similarly affected unrelated family (PMID: 22949511, 26538303). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 115 of the FKBP10 protein (p.Arg115Gln). This variant is present in population databases (rs387906960, gnomAD 0.003%). This missense change has been observed in individual(s) with osteogenesis imperfecta (PMID: 20839288, 26538303, 30715774). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 30634). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FKBP10 protein function. For these reasons, this variant has been classified as Pathogenic. -
Osteogenesis imperfecta Pathogenic:1
Variant summary: FKBP10 c.344G>A (p.Arg115Gln) results in a conservative amino acid change located in the FKBP-type peptidyl-prolyl cis-trans isomerase domain (IPR001179) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 250756 control chromosomes. c.344G>A has been reported in the literature as a homozygous and compound heterozygous genotype in multiple individuals affected with autosomal recessive Osteogenesis Imperfecta (example, Umair_2016, Kelley_2011, Schwarze_2013). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
