Description

The c.1123C>G (p.P375A) alteration is located in exon 6 (coding exon 5) of the CHRNA2 gene. This alteration results from a C to G substitution at nucleotide position 1123, causing the proline (P) at amino acid position 375 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
