Genes affected

FAM120B (HGNC:21109): (family with sequence similarity 120 member B) Predicted to be involved in fat cell differentiation and peroxisome proliferator activated receptor signaling pathway. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

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: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
