Genes affected

DLL4 (HGNC:2910): (delta like canonical Notch ligand 4) This gene is a homolog of the Drosophila delta gene. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.58).
• BP6: Variant 15-40929984-C-A is Benign according to our data. Variant chr15-40929984-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 1997548.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.166 with no splicing effect.
