Genes affected
PPIB (HGNC:9255): (peptidylprolyl isomerase B) The protein encoded by this gene is a cyclosporine-binding protein and is mainly located within the endoplasmic reticulum. It is associated with the secretory pathway and released in biological fluids. This protein can bind to cells derived from T- and B-lymphocytes, and may regulate cyclosporine A-mediated immunosuppression. Variants have been identified in this protein that give rise to recessive forms of osteogenesis imperfecta. [provided by RefSeq, Oct 2009]
SNX22 (HGNC:16315): (sorting nexin 22) The protein encoded by this gene is a sorting nexin that is found in the cytoplasm, where it interacts with membrane-bound phosphatidylinositol 3-phosphate. The encoded protein may play a role in intracellular trafficking. Two transcript variants, one protein-coding and the other not protein-coding, have been found for this gene. [provided by RefSeq, Dec 2012]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PM1
In a chain Peptidyl-prolyl cis-trans isomerase B (size 182) in uniprot entity PPIB_HUMAN there are 4 pathogenic changes around while only 1 benign (80%) in NM_000942.5
PP3
MetaRNN computational evidence supports a deleterious effect, 0.872
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000417 (61/1461892) while in subpopulation EAS AF = 0.00116 (46/39700). AF 95% confidence interval is 0.000892. There are 0 homozygotes in GnomAdExome4. There are 34 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
