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]

Ambry Genetics

Oct 12, 2021

The c.10C>T (p.P4S) 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 10, causing the proline (P) at amino acid position 4 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
