NM_000448.3(RAG1):c.2442G>T is a missense variant predicted to cause substitution of Glutamic Acid by Aspartic Acid at amino acid 814 (p.Glu814Asp). This missense variant is located in the core domain (amino acids 387-1011) (PM1_Supporting). The filtering allele frequency (the upper threshold of the 95% CI of 3/44724) of the c.2442G>T variant in RAG1 is 0.00001779 for Admixed American chromosomes by gnomAD v4, which is lower than the ClinGen SCID VCEP threshold (<0.000102) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal recessive severe combined immunodeficiency due to RAG1 deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: PM1_Supporting,PM2_Supporting(VCEP specifications version 1).
