Genes affected
DLL3 (HGNC:2909): (delta like canonical Notch ligand 3) This gene encodes a member of the delta protein ligand family. This family functions as Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. Mutations in this gene cause autosomal recessive spondylocostal dysostosis 1. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.119G>A (p.G40D) alteration is located in exon 2 (coding exon 2) of the DLL3 gene. This alteration results from a G to A substitution at nucleotide position 119, causing the glycine (G) at amino acid position 40 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
