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=-0.45).

BP6

Variant 20-10648102-G-A is Benign according to our data. Variant chr20-10648102-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 255549.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.264 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000992 (151/152272) while in subpopulation SAS AF = 0.0029 (14/4826). AF 95% confidence interval is 0.00175. There are 0 homozygotes in GnomAd4. There are 67 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 151 AD gene.
