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.

The p.(His65Arg) has been identified in the heterozygous state in a patient with a clinical suspicion of Silver Russell syndrome. ). His65 is located within the second EGF-like motif of the extracellular domain of DLK1. This variant was inherited from her healthy mother, who carried the same heterozygous variant. As DLK1 is a maternally imprinted/paternally expressed gene, this variant is unlikely to explain the phenotype of the patient -
