Description

A Hemizygote Missense variant c.770G>T in Exon 5 of the CD40LG gene that results in the amino acid substitution p.Gly257Val was identified. The observed variant has a minimum allele frequency of 00/00% in gnomAD exomes and genomes, respectively. The severity of the impact of this variant on the protein is high, based on the effect of the protein and REVEL score . Rare Exome Variant Ensemble Learner (REVEL) is an ensembl method for predicting the pathogenicity of missense variants based on a combination of scores from 13 individual tools: MutPred, FATHMM v2.3, VEST 3.0, PolyPhen-2, SIFT, PROVEAN, MutationAssessor, MutationTaster, LRT, GERP++, SiPhy, phyloP, and phastCons. The REVEL score for an individual missense variant can range from 0 to 1, with higher scores reflecting greater likelihood that the variant is disease-causing. Based on the above evidence this variant has been classified as Likely Pathogenic according to the ACMG guidelines.
