NM_000448.3:c.15C>G

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_000448.3:c.15C>G variant in RAG1 is a missense variant predicted to cause a substitution of phenylalanine by leucine at amino acid 5 (p.Phe5Leu). The Popmax filtering allele frequency of this variant in gnomAD v2.1.1 is 0.00000292, which is lower than the SCID-VCEP’s threshold for PM2 (<0.000102). No homozygous individual has been observed in the gnomAD v2.1.1 (PM2_Supporting). This variant has not been reported in the literature in individuals with SCID. In ClinVar, the variant was reported in one affected individual who didn't have a second RAG1 variant, and the variant was classified as a Variant of Uncertain Significance (Invitae, SCV001420312.4). There is no functional evidence for this variant. Due to insufficient evidence, this variant is classified as a variant of uncertain significance for SCID. ACMG/AMP criteria applied, as specified by the ClinGen SCID-VCEP: PM2_supporting (SCID VCEP specifications version 1.0).

Genes affected
RAG1 (HGNC:9831): (recombination activating 1) The protein encoded by this gene is involved in activation of immunoglobulin V-D-J recombination. The encoded protein is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG2. Defects in this gene can be the cause of several diseases.
