Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 1P and 12B. PP3 BP4_Strong BA1

The NM_022075.5(CERS2):​c.344A>C​(p.Glu115Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.187 in 1,609,316 control chromosomes in the GnomAD database, including 31,143 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E115G) has been classified as Uncertain significance.

Genes affected

CERS2 (HGNC:14076): (ceramide synthase 2) This gene encodes a protein that has sequence similarity to yeast longevity assurance gene 1. Mutation or overexpression of the related gene in yeast has been shown to alter yeast lifespan. The human protein may play a role in the regulation of cell growth. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -11 ACMG points.

• PP3: Multiple lines of computational evidence support a deleterious effect 6: Cadd, FATHMM_MKL, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]
• BP4: Computational evidence support a benign effect (MetaRNN=0.001857996).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.205 is higher than 0.05.
