Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1240C>T (p.R414C) alteration is located in exon 5 (coding exon 5) of the CHRNA10 gene. This alteration results from a C to T substitution at nucleotide position 1240, causing the arginine (R) at amino acid position 414 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
