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 Likely_benign. Variant got -5 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.
BP4
Computational evidence support a benign effect (MetaRNN=0.39471295).
BP6
Variant 20-10641549-G-A is Benign according to our data. Variant chr20-10641549-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 468657.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=2}.
BS2
High AC in GnomAd4 at 5 AD gene.

The c.2827C>T (p.P943S) alteration is located in exon 23 (coding exon 23) of the JAG1 gene. This alteration results from a C to T substitution at nucleotide position 2827, causing the proline (P) at amino acid position 943 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
