Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PP2PP3_StrongPP5
The NM_000214.3(JAG1):c.110T>C(p.Leu37Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. L37L) has been classified as Likely benign.

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 Pathogenic. Variant got 10 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 4 uncertain in NM_000214.3
PM2
?
Very rare variant in population databases, with high coverage;
PP2
?
Missense variant where missense usually causes diseases, JAG1
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.993
PP5
?
Variant 20-10672978-A-G is Pathogenic according to our data. Variant chr20-10672978-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 7625.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr20-10672978-A-G is described in Lovd as [Pathogenic].
