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]

In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Splice predictors suggests this variant may impact gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 32459320) -

The JAG1 c.3281G>A variant is predicted to result in the amino acid substitution p.Arg1094Gln. This variant was reported in an individual with hypothyroidism (Yamaguchi et al 2020. PubMed ID: 32459320). This variant is reported in 0.023% of alleles in individuals of European (Non-Finnish) descent in gnomAD, which is likely too common to be a primary cause of disease. Although we suspect this variant may be benign, at this time, the clinical significance is uncertain due to the absence of conclusive functional and genetic evidence. -
