Genes affected

WFS1 (HGNC:12762): (wolframin ER transmembrane glycoprotein) This gene encodes a transmembrane protein, which is located primarily in the endoplasmic reticulum and ubiquitously expressed with highest levels in brain, pancreas, heart, and insulinoma beta-cell lines. Mutations in this gene are associated with Wolfram syndrome, also called DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness), an autosomal recessive disorder. The disease affects the brain and central nervous system. Mutations in this gene can also cause autosomal dominant deafness 6 (DFNA6), also known as DFNA14 or DFNA38. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.92).

BP6

Variant 4-6301469-C-T is Benign according to our data. Variant chr4-6301469-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 178594.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-3.21 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00244 (372/152376) while in subpopulation AFR AF = 0.00839 (349/41592). AF 95% confidence interval is 0.00767. There are 1 homozygotes in GnomAd4. There are 166 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
