Genes affected

RPEL1 (HGNC:45241): (ribulose-5-phosphate-3-epimerase like 1) Predicted to enable metal ion binding activity and ribulose-phosphate 3-epimerase activity. Predicted to be involved in cellular carbohydrate metabolic process; pentose catabolic process; and pentose-phosphate shunt, non-oxidative branch. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

NT5C2 (HGNC:8022): (5'-nucleotidase, cytosolic II) This gene encodes a hydrolase that serves as an important role in cellular purine metabolism by acting primarily on inosine 5'-monophosphate and other purine nucleotides. [provided by RefSeq, Oct 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2729293).

The c.92C>T (p.A31V) alteration is located in exon 1 (coding exon 1) of the RPEL1 gene. This alteration results from a C to T substitution at nucleotide position 92, causing the alanine (A) at amino acid position 31 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
