Genes affected

PYCR3 (HGNC:25846): (pyrroline-5-carboxylate reductase 3) This gene encodes a protein that belongs to the pyrroline-5-carboxylate reductase family of enzymes. Members of this family catalyze the final step in proline biosynthesis, converting pyrroline-5-carboxylate to proline. Glutamate and ornithine are precursors in the synthesis of proline. The protein encoded by this gene is a cytoplasmic enzyme involved in the biosynthesis of proline from ornithine. [provided by RefSeq, Aug 2016]

The c.794T>C (p.L265P) alteration is located in exon 6 (coding exon 6) of the PYCRL gene. This alteration results from a T to C substitution at nucleotide position 794, causing the leucine (L) at amino acid position 265 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
