Genes affected

JAG1 (HGNC:6188): (jagged canonical Notch ligand 1) The jagged 1 protein encoded by JAG1 is the human homolog of the Drosophilia jagged protein. Human jagged 1 is the ligand for the receptor notch 1, the latter is involved in signaling processes. Mutations that alter the jagged 1 protein cause Alagille syndrome. Jagged 1 signalling through notch 1 has also been shown to play a role in hematopoiesis. [provided by RefSeq, Nov 2019]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PP2

Missense variant in the JAG1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 32 curated pathogenic missense variants (we use a threshold of 10). The gene has 65 curated benign missense variants. Gene score misZ: 3.2459 (above the threshold of 3.09). Trascript score misZ: 5.2848 (above the threshold of 3.09). GenCC associations: The gene is linked to tetralogy of fallot, Alagille syndrome due to a JAG1 point mutation, Charcot-Marie-Tooth disease, axonal, Type 2HH.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.945

BS2

Review Status: criteria provided, single submitter

Collection Method: curation

This variant is interpreted as Likely Pathogenic, for Tetralogy of Fallot. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PS3 => Well-established functional studies show a deleterious effect (https://www.ncbi.nlm.nih.gov/pubmed/20437614). -
