Genes affected

ITGB3 (HGNC:6156): (integrin subunit beta 3) The ITGB3 protein product is the integrin beta chain beta 3. Integrins are integral cell-surface proteins composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. Integrin beta 3 is found along with the alpha IIb chain in platelets. Integrins are known to participate in cell adhesion as well as cell-surface mediated signalling. [provided by RefSeq, Jul 2008]

Benign, reviewed by expert panel	curation	ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen	May 07, 2021	The NM_000212.2:c.342T>C variant, which leads to a synonymous change, Ile114Ile, is reported at a high frequency in the African population in gnomAD and ExAC (0.05). In-silico splicing predictors do not predict splicing impact. PMID: 27469266 reports on this and other polymorphic, non-causal variants found in linkage disequilibrium with deleterious mutations in GT patients. Ile114Ile is classified as a benign variant. GT-specific criteria applied: BA1, BP4, and BP7. -
Benign, 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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
