Severe Combined Immunodeficiency Disease VCEP

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).

Met criteria codes

• BA1: 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).
• BS2_Supporting: Furthermore, 321 adult homozygous were described in GnomAD v.4, meeting BS2_Supporting criteria.
