Genes affected

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]

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.791

Collection Method: clinical testing

The c.6865T>C (p.Y2289H) alteration is located in exon 37 (coding exon 35) of the DOPEY1 gene. This alteration results from a T to C substitution at nucleotide position 6865, causing the tyrosine (Y) at amino acid position 2289 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
