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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: VDR c.1085C>T (p.Thr362Ile) results in a non-conservative amino acid change located in the nuclear hormone receptor, ligand-binding domain (IPR000536) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00027 in 1614050 control chromosomes, predominantly at a frequency of 0.0053 within the African or African-American subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database (v4) exceeds the estimated maximal expected allele frequency for a pathogenic variant in VDR causing Vitamin D-Dependent Rickets Type II With Alopecia phenotype. To our knowledge, no occurrence of c.1085C>T in individuals affected with Vitamin D-Dependent Rickets Type II With Alopecia and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 754732). Based on the evidence outlined above, the variant was classified as benign. -
