Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_006005.3(WFS1):c.2611G>A(p.Val871Met) variant causes a missense change. The variant allele was found at a frequency of 0.00993 in 1,613,120 control chromosomes in the GnomAD database, including 92 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V871G) has been classified as Uncertain significance.

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 -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0069407225).

BP6

Variant 4-6302406-G-A is Benign according to our data. Variant chr4-6302406-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 95325.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00731 (1113/152328) while in subpopulation NFE AF = 0.0117 (793/68016). AF 95% confidence interval is 0.011. There are 5 homozygotes in GnomAd4. There are 534 alleles in the male GnomAd4 subpopulation. Median coverage is 35. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AD,AR,Unknown gene
