ClinVar

Description

The TNFRSF13B p.R14C variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs370503383) and in control databases in 12 of 251340 chromosomes at a frequency of 0.00004774 (freq: 0.00007037) (Genome Aggregation Database March 6, 2019, v2.1.1). The p.R14 residue is not conserved in mammals and computational analyses (MUT Assesor, PolyPhen-2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
