Genes affected

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

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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BP6: Variant 1-42473350-C-G is Benign according to our data. Variant chr1-42473350-C-G is described in ClinVar as [Benign]. Clinvar id is 1263588.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.175 is higher than 0.05.
