Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BS1BS2_Supporting
This summary comes from the ClinGen Evidence Repository: The c.362G>A (NM_000215.4) variant in JAK3 is a missense variant predicted to cause the substitution of Arginine by Histidine at amino acid 121 (p.Arg121His).The popmax filtering allele frequency in gnomAD v.4 is 0.0001262 (based on 11/58232 alleles in the Admixed American population), which is higher than the SCID VCEP established threshold of <0.000115 for PM2_Supporting and lower than >0.00447 (BA1 threshold) and 0.001 (BS1 threshold);However, the highest MAF in the Ashkenazi Jewish population is 0.001469 (43/29280 alleles), which is above the SCID VCEP established threshold of >0.00100. As this population is not known to have a higher prevalence of SCID, this is considered to meet BS1. There is a homozygote in gnomAD v.4 in the Ashkenazi Jewish population (43/29280 alleles), BS2_Supporting.To our knowledge, this variant has not been reported in the literature in individuals affected with JAK3-related conditions or in functional studies.In summary, this variant meets the criteria to be classified as Likely Benign for autosomal recessive T-B+ severe combined immunodeficiency due to JAK3 deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP. Criteria applied: BS1 and BS2_Supporting (VCEP specifications version 1.0). LINK:https://erepo.genome.network/evrepo/ui/classification/CA9302185/MONDO:0010938/121
