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 GeneticsMar 20, 2024The c.31G>C (p.A11P) alteration is located in exon 2 (coding exon 1) of the PPCDC gene. This alteration results from a G to C substitution at nucleotide position 31, causing the alanine (A) at amino acid position 11 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
