Genes affected

PGM3 (HGNC:8907): (phosphoglucomutase 3) This gene encodes a member of the phosphohexose mutase family. The encoded protein mediates both glycogen formation and utilization by catalyzing the interconversion of glucose-1-phosphate and glucose-6-phosphate. A non-synonymous single nucleotide polymorphism in this gene may play a role in resistance to diabetic nephropathy and neuropathy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

DOP1A (HGNC:21194): (DOP1 leucine zipper like protein A) Predicted to be involved in Golgi to endosome transport and endoplasmic reticulum organization. Predicted to be located in Golgi membrane. Predicted to be active in endosome and trans-Golgi network. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BP6: Variant 6-83166476-A-C is Benign according to our data. Variant chr6-83166476-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 3049258.Status of the report is no_assertion_criteria_provided, 0 stars.
