Labcorp Genetics (formerly Invitae), Labcorp RCV001204096 SCV001375287 uncertain significance Leukocyte adhesion deficiency 1 2022-07-23 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 245 of the ITGB2 protein (p.Ala245Thr). This variant is present in population databases (rs144280462, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ITGB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 935493). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
Ambry Genetics RCV002561140 SCV003686487 uncertain significance Inborn genetic diseases 2022-07-19 criteria provided, single submitter clinical testing The c.733G>A (p.A245T) alteration is located in exon 6 (coding exon 5) of the ITGB2 gene. This alteration results from a G to A substitution at nucleotide position 733, causing the alanine (A) at amino acid position 245 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
