Genes affected

PRKCSH (HGNC:9411): (PRKCSH beta subunit of glucosidase II) This gene encodes the beta-subunit of glucosidase II, an N-linked glycan-processing enzyme in the endoplasmic reticulum. The encoded protein is an acidic phosphoprotein known to be a substrate for protein kinase C. Mutations in this gene have been associated with the autosomal dominant polycystic liver disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

ODAD3 (HGNC:28303): (outer dynein arm docking complex subunit 3) This gene encodes a protein containing coiled-coil domains. The encoded protein functions in outer dynein arm assembly and is required for motile cilia function. Mutations in this gene result in primary ciliary dyskinesia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.63).
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000997 (97/973160) while in subpopulation SAS AF= 0.000919 (67/72910). AF 95% confidence interval is 0.000742. There are 1 homozygotes in gnomad4_exome. There are 73 alleles in male gnomad4_exome subpopulation. Median coverage is 13. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High AC in GnomAd at 15 AD gene.
