Prevalence and impact of the KIT M541L variant in patients with mastocytosis.

Abstract excerpt

Activating mutations in KIT, particularly D816V, have been associated with mastocytosis. Additionally, expression of heterozygous KIT M541L has been primarily reported in patients with pediatric mastocytosis. We thus examined the prevalence of this variant in pediatric and adult patients with mastocytosis (n = 100) compared to ancestry-matched 1000 genomes controls (n = 500) and patients with idiopathic...
