The DOCK8 c.4346C>T variant is predicted to result in the amino acid substitution p.Ser1449Leu. This variant has been reported in the homozygous state in three related Saudi patients from a highly consanguineous family (Al Shekaili et al. 2017. PubMed ID: 27890707). Of note, these individuals were also homozygous for a splicing variant, c.4626+5G>A, in DOCK8 that was predicted to impact splicing based on splicing predication programs and abolish protein product via western blot analysis (Alamut Visual Plus v1.6.1; Al Shekaili et al. 2017. PubMed ID: 27890707). This variant was also reported in the compound heterozygous state in an individual with suspected primary immunodeficiency (Table E2 - Platt et al. 2021. PubMed ID: 32888943). This variant is reported in 0.017% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-428369-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
