Description

The c.1643G>A (p.R548Q) alteration is located in exon 12 (coding exon 12) of the CHAT gene. This alteration results from a G to A substitution at nucleotide position 1643, causing the arginine (R) at amino acid position 548 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
