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]

The c.2150G>A (p.C717Y) alteration is located in exon 10 (coding exon 10) of the DLL1 gene. This alteration results from a G to A substitution at nucleotide position 2150, causing the cysteine (C) at amino acid position 717 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
