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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 02, 2024The c.418C>T (p.P140S) alteration is located in exon 4 (coding exon 4) of the PYCRL gene. This alteration results from a C to T substitution at nucleotide position 418, causing the proline (P) at amino acid position 140 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
