Collection Method: clinical testing

The c.137C>A (p.A46E) alteration is located in exon 1 (coding exon 1) of the NEUROG1 gene. This alteration results from a C to A substitution at nucleotide position 137, causing the alanine (A) at amino acid position 46 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
