RCV001128133 | SCV005439096 | likely benign | Glanzmann thrombasthenia | 2024-12-17 | reviewed by expert panel | curation | The c.3061-4C>T variant in ITGA2B is an intronic variant located in intron 29. The variant is not predicted by SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not highly conserved as shown by phyloP score of 1.44101 (BP4, BP7). The highest population minor allele frequency in gnomAD v4.1.0 is 0.00006687 (3/44864 alleles) in the East Asian population, which is lower than the ClinGen PD VCEP threshold (<0.0001; PM2_Supporting). This variant was observed by Illumina as part of a predisposition screen in an ostensibly healthy population, however, no cases of the variant segregating in GT patients were found in the literature. Due to conflicting evidence, this variant is classified as likely benign for autosomal recessive Glanzmann thrombasthenia based on the ACMG/AMP criteria applied, as specified by the ClinGen PD-VCEP: BP4, BP7 and PM2_Supporting (VCEP specifications version 2.1.0). |

RCV001128133 | SCV001287540 | uncertain significance | Glanzmann thrombasthenia | 2018-01-12 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |
