Genes affected

PPCDC (HGNC:28107): (phosphopantothenoylcysteine decarboxylase) Biosynthesis of coenzyme A (CoA) from pantothenic acid (vitamin B5) is an essential universal pathway in prokaryotes and eukaryotes. PPCDC (EC 4.1.1.36), one of the last enzymes in this pathway, converts phosphopantothenoylcysteine to 4-prime-phosphopantetheine (Daugherty et al., 2002 [PubMed 11923312]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Jun 24, 2022

The c.385C>G (p.R129G) alteration is located in exon 5 (coding exon 4) of the PPCDC gene. This alteration results from a C to G substitution at nucleotide position 385, causing the arginine (R) at amino acid position 129 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
