Genes affected

FKBP6 (HGNC:3722): (FKBP prolyl isomerase family member 6 (inactive)) The protein encoded by this gene is a cis-trans peptidyl-prolyl isomerase that may function in immunoregulation and basic cellular processes involving protein folding and trafficking. This gene is located in a chromosomal region that is deleted in Williams-Beuren syndrome. Defects in this gene may cause male infertility. There are multiple pseudogenes for this gene located nearby on chromosome 7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00113 (172/152260) while in subpopulation EAS AF = 0.0314 (163/5184). AF 95% confidence interval is 0.0275. There are 7 homozygotes in GnomAd4. There are 96 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 7 AR gene
