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 -2 ACMG points.

PM1

In a domain EGF-like 8; calcium-binding (size 36) in uniprot entity JAG1_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_000214.3

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.

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000026 (38/1461828) while in subpopulation EAS AF= 0.000907 (36/39700). AF 95% confidence interval is 0.000673. There are 0 homozygotes in gnomad4_exome. There are 22 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 38 AD gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
