Genes affected

ID4 (HGNC:5363): (inhibitor of DNA binding 4) This gene encodes a member of the inhibitor of DNA binding (ID) protein family. The encoded protein lacks DNA binding ability, and instead regulates gene expression through binding to and inhibiting basic helix-loop-helix transcription factors. This protein has been implicated in the regulation of diverse cellular processes that play a role in development and tumorigenesis. [provided by RefSeq, Aug 2017]

The c.172G>A (p.D58N) alteration is located in exon 1 (coding exon 1) of the ID4 gene. This alteration results from a G to A substitution at nucleotide position 172, causing the aspartic acid (D) at amino acid position 58 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
