A heterozygous missense variant, NM_001009944.2(PKD1):c.7927C>T, has been identified in exon 21 of 46 of the PKD1 gene. The variant is predicted to result in a major amino acid change from arginine to cysteine at position 2643 of the protein (NP_001009944.2(PKD1):p.(Arg2643Cys)). The arginine at this position has high conservation (100 vertebrates, UCSC), and is located within the GPCR-autoproteolysis inducing (Arac, D. et al., 2012) functional domain. In silico predictions for this variant are consistently pathogenic (Polyphen, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD database at a frequency of 0.0004% (1 heterozygote). An alternative residue change has been reported in the gnomAD database at a frequency of 0.008%. The variant has been previously described as pathogenic in patients with autosomal dominant polycystic kidney disease (ADPKD) (Garcia-Gonzalez, M.A. et al., 2007; Mallawaarachchi, A.C. et al., 2016). Additionally, studies showed that this variant impacts protein function (Garcia-Gonzalez, M.A. et al., 2007). Despite analysis of maternal sample, the inheritance of this variant remains unsolved. Based on the information available at the time of curation, this variant has been classified as PATHOGENIC.
