Combined immunodeficiency due to LRBA deficiency Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 2119 of the LRBA protein (p.Asp2119His). This variant is present in population databases (rs142598024, gnomAD 0.03%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with LRBA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1018660). 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 LRBA protein function with a positive 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.
Inborn genetic diseases Uncertain:1
The c.6355G>C (p.D2119H) alteration is located in exon 41 (coding exon 40) of the LRBA gene. This alteration results from a G to C substitution at nucleotide position 6355, causing the aspartic acid (D) at amino acid position 2119 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
