Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_006005.3(WFS1):c.353A>C(p.Asp118Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000494 in 1,608,038 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. D118E) 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]

The WFS1 c.353A>C; p.Asp118Ala variant (rs71524349), is reported in the literature in an individual with prelingual nonsyndromic hearing loss (Sommen 2016); however, inheritance and specific clinical information were not reported for this individual. This variant has also been observed in our laboratory in the homozygous state in an individual who had an alternate molecular basis for disease. This variant is found in the African population with an allele frequency of 0.90% (203/22,568 alleles) in the Genome Aggregation Database and is reported as benign/likely benign in ClinVar (Variation ID: 178584). Based on the available information, this variant is classified as likely benign. -
