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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 16, 2024The c.410C>T (p.P137L) alteration is located in exon 5 (coding exon 4) of the PPCDC gene. This alteration results from a C to T substitution at nucleotide position 410, causing the proline (P) at amino acid position 137 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
