Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2
The NM_012452.3(TNFRSF13B):āc.568G>Cā(p.Gly190Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000185 in 1,614,064 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Variant summary: TNFRSF13B c.568G>C (p.Gly190Arg) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00026 in 250678 control chromosomes in the gnomAD database, including 1 homozygotes. The observed variant frequency is approximately 92.15 fold of the estimated maximal expected allele frequency for a pathogenic variant in TNFRSF13B causing Common Variable Immunodeficiency phenotype (2.9e-06), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.568G>C in individuals affected with Common Variable Immunodeficiency and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as likely benign, and one laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -
