Genes affected

ADPGK (HGNC:25250): (ADP dependent glucokinase) ADPGK (EC 2.7.1.147) catalyzes the ADP-dependent phosphorylation of glucose to glucose-6-phosphate and may play a role in glycolysis, possibly during ischemic conditions (Ronimus and Morgan, 2004 [PubMed 14975750]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07009521).

The c.1419T>G (p.I473M) alteration is located in exon 7 (coding exon 7) of the ADPGK gene. This alteration results from a T to G substitution at nucleotide position 1419, causing the isoleucine (I) at amino acid position 473 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
