Genes affected

CERK (HGNC:19256): (ceramide kinase) CERK converts ceramide to ceramide 1-phosphate (C1P), a sphingolipid metabolite. Both CERK and C1P have been implicated in various cellular processes, including proliferation, apoptosis, phagocytosis, and inflammation (Kim et al., 2006 [PubMed 16488390]).[supplied by OMIM, Mar 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0053140223).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0136 (2074/152210) while in subpopulation AFR AF = 0.0477 (1982/41516). AF 95% confidence interval is 0.046. There are 40 homozygotes in GnomAd4. There are 1035 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 40 AR gene
