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]

The c.704G>A (p.S235N) 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 704, causing the serine (S) at amino acid position 235 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
