Variant rs145895196 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 3P and 6B. PM5PP2BP4_ModerateBS2

The NM_000214.3(JAG1):c.2810G>T(p.Arg937Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,614,156 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R937Q) 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 Likely_benign. Variant got -3 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr20-10641566-C-T is described in Lovd as [Pathogenic].

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), JAG1. . Gene score misZ 3.2459 (greater than the threshold 3.09). Trascript score misZ 5.2848 (greater than threshold 3.09). GenCC has associacion of gene with tetralogy of fallot, Alagille syndrome due to a JAG1 point mutation, Charcot-Marie-Tooth disease, axonal, Type 2HH.

BP4

Computational evidence support a benign effect (MetaRNN=0.22420356).

BS2

High AC in GnomAdExome4 at 7 AD gene.
