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: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 4 benign, 21 uncertain in NM_006005.3
PM4
Nonframeshift variant in NON repetitive region in NM_006005.3. Strenght limited to Supporting due to length of the change: 1aa.
PP5
Variant 4-6301029-GTCT-G is Pathogenic according to our data. Variant chr4-6301029-GTCT-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 212611.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
