Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP7BP4
This summary comes from the ClinGen Evidence Repository: NM_001754.5(RUNX1):c.444C>T (p.Thr148=) is a synonymous variant which has a SpliceAI score of 0.00 and a PhyloP score of -6.58, indicating no predicted impact on splicing and lack of conservation (BP4, BP7). This variant is present in gnomAD but not at an elevated frequency, so no population codes were applied. In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BP4, BP7.

Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 Benign:2
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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -

Inborn genetic diseases Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
RUNX1-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
