Description

The p.P562L variant (also known as c.1685C>T), located in coding exon 5 of the CHRNA4 gene, results from a C to T substitution at nucleotide position 1685. The proline at codon 562 is replaced by leucine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
