Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BP7
This summary comes from the ClinGen Evidence Repository: After a comprehensive literature search of the synonymous variant NM_000212.3(ITGB3):c.201G>A (p.Lys67=), no individuals with Glanzmann thrombasthenia were reported with the variant and has only been observed in a ostensibly healthy population. The variant has a minor allele frequency of 0.00110 (38/34590 alleles) in the Latino population in gnomAD, which does not meet our threshold criteria for PM2_supporting or BS1. In silico predictor spliceAI revealed that the synonymous mutation is not expected to impact splicing and a PhyloP score of -0.08 shows that the nucleotide position is not highly conserved (BP4, 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: BP4, BP7 (PD VCEP specifications version 2.1).

Likely benign, reviewed by expert panel | curation | ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen | Jun 01, 2023 | After a comprehensive literature search of the synonymous variant NM_000212.3(ITGB3):c.201G>A (p.Lys67=), no individuals with Glanzmann thrombasthenia were reported with the variant and has only been observed in a ostensibly healthy population.

Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | 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. - |
