Variant summary
Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM5PP2PP3_ModeratePP5
The NM_000448.3(RAG1):c.335G>A(p.Arg112His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,614,018 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R112C) has been classified as Likely pathogenic.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 112 of the RAG1 protein (p.Arg112His). This variant is present in population databases (rs749223640, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with RAG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 427093). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RAG1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

In silico analysis supports that this missense variant does not alter protein structure/function; Observed in a patient with autoimmune neutropenia with a pathogenic variant in published literature, but it is not known whether the variants occurred on the same (in cis) or on different (in trans) chromosomes (Farmer et al., 2019); This variant is associated with the following publications: (PMID: 27825771, 30809743, 26884280, Baroudi-2019[Abstract], 30877075) -
