Genes affected

VDR (HGNC:12679): (vitamin D receptor) This gene encodes vitamin D3 receptor, which is a member of the nuclear hormone receptor superfamily of ligand-inducible transcription factors. This receptor also functions as a receptor for the secondary bile acid, lithocholic acid. Downstream targets of vitamin D3 receptor are principally involved in mineral metabolism, though this receptor regulates a variety of other metabolic pathways, such as those involved in immune response and cancer. Mutations in this gene are associated with type II vitamin D-resistant rickets. A single nucleotide polymorphism in the initiation codon results in an alternate translation start site three codons downstream. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. A recent study provided evidence for translational readthrough in this gene, and expression of an additional C-terminally extended isoform via the use of an alternative in-frame translation termination codon.

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. -
