Severe Combined Immunodeficiency Disease VCEP
NM_000022.4:c.631C>T is a missense variant predicted to cause substitution of Arginine by Cysteine at amino acid 211 (p. Arg211Cys). The highest population minor allele frequency in gnomAD v4 is 0.0005167 (31/60000) in Admixed American population (PM2_Supporting, BS1, and BA1 are not met). The variant has been reported to segregate with SCID in 2 affected family members from 1 family (PP1_moderate; PMID :8051429). Patient was found heterozygous for R211C & L107P which is classified as likely pathogenic by SCID VCEP (1 pt.) (PM3) (PMID: 2166947).Another missense variant [c.632G>A, p.Arg211His)] in the same codon has been classified as pathogenic for SCID by the ClinGen SCID VCEP (PM5). In summary, this variant meets the criteria to be classified as a Likely Pathogenic variant for autosomal recessive severe combined immunodeficiency due to ADA deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: PP1_moderate,PM3,PM5(VCEP specifications version 1).
