RCV001818143 | SCV002069217 | likely pathogenic | not provided | 2018-07-16 | criteria provided, single submitter | clinical testing | DNA sequence analysis of the VDR gene demonstrated a sequence change, c.1036G>A, in exon 11 that results in an amino acid change, p.Val346Met. This particular amino acid change has been described in the homozygous state in three affected family members with hereditary vitamin D-resistant rickets (HVDRR) (Arita et. al., 2008). In vitro functional assays demonstrated impaired transcriptional activity, and impaired ligand binding affinity for this variant (Tamura et. al., 2017). This sequence change has been described in the gnomAD database with a low population frequency of 0.0004% (dbSNP rs267607169). The p.Val346Met change affects a highly conserved amino acid residue located in a domain of the VDR protein that is known to be functional. The p.Val346Met substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change is the likely cause of the indicated phenotype, however functional studies have not been performed to prove this conclusively. |
