Description

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this variant affects STK4 protein function (PMID: 26801501). This variant has been observed in individual(s) with autosomal recessive combined immunodeficiency (PMID: 26801501). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs749441226, ExAC 0.02%). This sequence change creates a premature translational stop signal (p.Arg148*) in the STK4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in STK4 are known to be pathogenic (PMID: 22174160).

Description

The c.442C>T;p.(Arg148*) variant creates a premature translational stop signal in the STK4 gene. It is expected to result in an absent or disrupted protein product - PVS1. ClinVar contains an entry for this variant (Clinvar ID: 1075656) - PS4_supporting. The variant is present at low allele frequencies population databases (rs749441226 – gnomAD 0.0001979%; ABraOM no frequency - https://abraom.ib.usp.br/) - PM2_supporting. In summary, the currently available evidence indicates that the variant is pathogenic.
