Genes affected

ABL1 (HGNC:76): (ABL proto-oncogene 1, non-receptor tyrosine kinase) This gene is a protooncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes, including cell division, adhesion, differentiation, and response to stress. The activity of the protein is negatively regulated by its SH3 domain, whereby deletion of the region encoding this domain results in an oncogene. The ubiquitously expressed protein has DNA-binding activity that is regulated by CDC2-mediated phosphorylation, suggesting a cell cycle function. This gene has been found fused to a variety of translocation partner genes in various leukemias, most notably the t(9;22) translocation that results in a fusion with the 5' end of the breakpoint cluster region gene (BCR; MIM:151410). Alternative splicing of this gene results in two transcript variants, which contain alternative first exons that are spliced to the remaining common exons. [provided by RefSeq, Aug 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ABL1. . Gene score misZ 2.5581 (greater than the threshold 3.09). Trascript score misZ 4.2755 (greater than threshold 3.09). GenCC has associacion of gene with congenital heart defects and skeletal malformations syndrome, connective tissue disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.95
• PP5: Variant 9-130873027-T-G is Pathogenic according to our data. Variant chr9-130873027-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376096.Status of the report is no_assertion_criteria_provided, 0 stars.
