Genes affected

ID2 (HGNC:5361): (inhibitor of DNA binding 2) The protein encoded by this gene belongs to the inhibitor of DNA binding family, members of which are transcriptional regulators that contain a helix-loop-helix (HLH) domain but not a basic domain. Members of the inhibitor of DNA binding family inhibit the functions of basic helix-loop-helix transcription factors in a dominant-negative manner by suppressing their heterodimerization partners through the HLH domains. This protein may play a role in negatively regulating cell differentiation. A pseudogene of this gene is located on chromosome 3. [provided by RefSeq, Aug 2011]

The c.391G>A (p.A131T) alteration is located in exon 2 (coding exon 2) of the ID2 gene. This alteration results from a G to A substitution at nucleotide position 391, causing the alanine (A) at amino acid position 131 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
