Role of the Nav1.7 R1150W amino acid change in susceptibility to symptomatic knee osteoarthritis and multiple regional pain.
OBJECTIVE: To assess the genetic association of pain in patients with knee osteoarthritis (OA) and those with multiple regional pain with the R1150W variant in the α-subunit of the voltage-gated sodium channel Na(V)1.7. METHODS: Knee OA patients from 2 UK cohorts (1,411 from the Genetics of Osteoarthritis and Lifestyle study and 267 from the Hertfordshire Cohort Study; 74% with symptomatic OA) with Western Ontario and McMaster Universities OA Index (WOMAC) pain scores were genotyped for rs674...Expand abstract
