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]

DLL1 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with nonspecific brain abnormalities and with or without seizures

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Laboratory for Molecular Medicine, G2P, Labcorp Genetics (formerly Invitae), Ambry Genetics
• autosomal dominant non-syndromic intellectual disability

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -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 VariationId 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 the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
• BS2: High AC in GnomAd4 at 3024 AD gene.
