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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.67).
BP6
Variant 20-10664002-A-G is Benign according to our data. Variant chr20-10664002-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 255560.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.96 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000078 (114/1461502) while in subpopulation NFE AF= 0.0000918 (102/1111664). AF 95% confidence interval is 0.0000769. There are 1 homozygotes in gnomad4_exome. There are 56 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High AC in GnomAd4 at 6 AD gene.

Ambry Genetics
Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. -
