Genes affected

RPIA (HGNC:10297): (ribose 5-phosphate isomerase A) The protein encoded by this gene is an enzyme, which catalyzes the reversible conversion between ribose-5-phosphate and ribulose-5-phosphate in the pentose-phosphate pathway. This gene is highly conserved in most organisms. The enzyme plays an essential role in the carbohydrate metabolism. Mutations in this gene cause ribose 5-phosphate isomerase deficiency. A pseudogene is found on chromosome 18. [provided by RefSeq, Mar 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.09189862).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000988 (15/151896) while in subpopulation AFR AF= 0.000339 (14/41358). AF 95% confidence interval is 0.000205. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Dec 19, 2022

The c.146C>T (p.S49F) alteration is located in exon 1 (coding exon 1) of the RPIA gene. This alteration results from a C to T substitution at nucleotide position 146, causing the serine (S) at amino acid position 49 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
