The c.481C>T (p.R161W) alteration is located in exon 1 (coding exon 1) of the NEUROG1 gene. This alteration results from a C to T substitution at nucleotide position 481, causing the arginine (R) at amino acid position 161 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
