Genes affected

PPCS (HGNC:25686): (phosphopantothenoylcysteine synthetase) Biosynthesis of coenzyme A (CoA) from pantothenic acid (vitamin B5) is an essential universal pathway in prokaryotes and eukaryotes. PPCS (EC 6.3.2.5), one of the last enzymes in this pathway, converts phosphopantothenate to phosphopantothenoylcysteine (Daugherty et al., 2002 [PubMed 11923312]).[supplied by OMIM, Mar 2008]

CCDC30 (HGNC:26103): (coiled-coil domain containing 30)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.38).
• BP6: Variant 1-42456589-C-T is Benign according to our data. Variant chr1-42456589-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 2167651.Status of the report is criteria_provided_single_submitter, 1 stars.
