ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen RCV000279371 SCV005061660 likely benign Glanzmann thrombasthenia 2024-02-20 reviewed by expert panel curation The c.799+15C>T variant in ITGA2B is an intronic variant which occurs in intron 7/29. The highest population minor allele frequency in gnomAD v4 is 0.002027 (21/10358 alleles) in the Ashkenazi Jewish population, which is higher than the ClinGen PD VCEP threshold (>0.00158), and therefore meets this criterion (BS1).This variant is not predicted by SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not conserved as shown by phyloP score of -0.8264 (BP7). In summary, this variant meets the criteria to be classified as likely benign for autosomal recessive Glanzmann Thrombasthenia based on the ACMG/AMP criteria applied, as specified by the ClinGen PD VCEP: BS1, BP7. (VCEP specifications version 2)
Illumina Laboratory Services, Illumina RCV000279371 SCV000403384 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.
