Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BS2_SupportingBA1

This summary comes from the ClinGen Evidence Repository: The c.394C>A (NM_000215.4) variant in JAK3 is a missense variant predicted to cause substitution of Proline by Threonine at amino acid 132 (p.Pro132Thr).The filtering allele frequency (the lower threshold of the 95% CI of 6500/74518) of the c.394C>A variant in JAK3 is 0.08599 for African/African American chromosomes by gnomAD v.4, which is higher than the ClinGen SCID VCEP threshold (>0.00447) for BA1, and therefore meets this criterion (BA1).Furthermore, 321 adult homozygous were described in GnomAD v.2.1.1, meeting BS2_Supporting criteria.In summary, this variant meets the criteria to be classified as 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: BA1 and BS2_Supporting (VCEP specifications version 1.0). LINK:https://erepo.genome.network/evrepo/ui/classification/CA160246/MONDO:0010938/121

Genes affected

JAK3 (HGNC:6193): (Janus kinase 3) The protein encoded by this gene is a member of the Janus kinase (JAK) family of tyrosine kinases involved in cytokine receptor-mediated intracellular signal transduction. It is predominantly expressed in immune cells and transduces a signal in response to its activation via tyrosine phosphorylation by interleukin receptors. Mutations in this gene are associated with autosomal SCID (severe combined immunodeficiency disease). [provided by RefSeq, Jul 2008]
