Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_000214.3(JAG1):​c.133G>T​(p.Val45Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000189 in 1,612,768 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V45M) 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]
LINC01752 (HGNC:52540): (long intergenic non-protein coding RNA 1752)

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.012577593).
BP6
Variant 20-10672955-C-A is Benign according to our data. Variant chr20-10672955-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 337761.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000368 (56/152294) while in subpopulation EAS AF = 0.00967 (50/5170). AF 95% confidence interval is 0.00754. There are 1 homozygotes in GnomAd4. There are 34 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 56 AD gene.
