Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 27, 2023	This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 788 of the BACH2 protein (p.Glu788Lys). This variant is present in population databases (rs757652995, gnomAD 0.009%). This missense change has been observed in individual(s) with immunoglobulin deficiency and intestinal inflammation (PMID: 28530713). ClinVar contains an entry for this variant (Variation ID: 625844). 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 not expected to disrupt BACH2 protein function with a negative predictive value of 80%. 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. -
