Genes affected

DLK1 (HGNC:2907): (delta like non-canonical Notch ligand 1) This gene encodes a transmembrane protein that contains multiple epidermal growth factor repeats that functions as a regulator of cell growth. The encoded protein is involved in the differentiation of several cell types including adipocytes. This gene is located in a region of chromosome 14 frequently showing unparental disomy, and is imprinted and expressed from the paternal allele. A single nucleotide variant in this gene is associated with child and adolescent obesity and shows polar overdominance, where heterozygotes carrying an active paternal allele express the phenotype, while mutant homozygotes are normal.

Ambry Genetics

Oct 20, 2023

The c.25C>G (p.R9G) alteration is located in exon 1 (coding exon 1) of the DLK1 gene. This alteration results from a C to G substitution at nucleotide position 25, causing the arginine (R) at amino acid position 9 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
