Is RAG1 p.Ala804Val (c.2411C>T) pathogenic?

RAG1 p.Ala804Val (c.2411C>T) is classified Likely pathogenic in RAG1 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-07-10). AlphaMissense: likely pathogenic (0.9653); Absent from gnomAD v4.1; Associated with combined immunodeficiency with skin granulomas.

What condition is associated with RAG1 p.Ala804Val (c.2411C>T)?

RAG1 p.Ala804Val (c.2411C>T) is associated with combined immunodeficiency with skin granulomas, severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive (ClinVar).

How common is RAG1 p.Ala804Val (c.2411C>T) in the general population?

RAG1 p.Ala804Val (c.2411C>T) is absent from gnomAD v4.1 (gnomAD).

How is Combined immunodeficiency with granulomatosis inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about RAG1 p.Ala804Val (c.2411C>T)?

AlphaMissense predicts likely pathogenic (score 0.9653) — an in-silico prediction, not a clinical call.
