Genes affected

ID3 (HGNC:5362): (inhibitor of DNA binding 3) The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with other HLH proteins. However, the encoded protein lacks a basic DNA-binding domain and therefore inhibits the DNA binding of any HLH protein with which it interacts. [provided by RefSeq, Aug 2011]

The c.86G>A (p.G29E) alteration is located in exon 1 (coding exon 1) of the ID3 gene. This alteration results from a G to A substitution at nucleotide position 86, causing the glycine (G) at amino acid position 29 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
