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.

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.002%). Stop-gained (nonsense) is predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant has been reported to be associated with VDR-related disorder (ClinVar ID: VCV000007757 / PMID: 9360557). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change creates a premature translational stop signal (p.Arg30*) in the VDR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in VDR are known to be pathogenic (PMID: 10204116, 24246681). This variant is present in population databases (rs121909801, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with vitamin D-dependent rickets (PMID: 9360557, 19049339). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 7757). For these reasons, this variant has been classified as Pathogenic. -
