Genes affected

NEUROG2 (HGNC:13805): (neurogenin 2) This gene encodes a neural-specific basic helix-loop-helix (bHLH) transcription factor that can specify a neuronal fate on ectodermal cells and is expressed in neural progenitor cells within the developing central and peripheral nervous systems. The protein product of this gene also plays a role in the differentiation and survival of midbrain dopaminergic neurons. [provided by RefSeq, Apr 2012]

Collection Method: clinical testing

The c.185G>A (p.G62E) alteration is located in exon 2 (coding exon 1) of the NEUROG2 gene. This alteration results from a G to A substitution at nucleotide position 185, causing the glycine (G) at amino acid position 62 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
