rs9333649, also known as G572R or Gly572Arg, is a SNP in the KCNH2 gene on chromosome 7.

Carrying one copy of the rs9333649(C) allele has been reported at least twice to be associated with long QT syndrome; see OMIM for discussion.

This variant meets the criteria published in 2013 by the ACMG regarding incidental findings in exome or genome sequencing, as a variant that they do recommend informing a patient about.[PMID 23788249OA-icon.png]
