Genes affected

DLL1 (HGNC:2908): (delta like canonical Notch ligand 1) DLL1 is a human homolog of the Notch Delta ligand and is a member of the delta/serrate/jagged family. It plays a role in mediating cell fate decisions during hematopoiesis. It may play a role in cell-to-cell communication. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BP6: Variant 6-170282680-G-A is Benign according to our data. Variant chr6-170282680-G-A is described in ClinVar as [Benign]. Clinvar id is 1268928.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0198 (3024/152368) while in subpopulation NFE AF= 0.0224 (1524/68032). AF 95% confidence interval is 0.0215. There are 83 homozygotes in gnomad4. There are 1739 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High AC in GnomAd at 3022 AD gene.
