Large-Scale Analysis of <i>KIT</i> Aberrations in Chinese Patients with Melanoma

Abstract

In China, the prevalent melanomas are acral and mucosal melanomas. KIT mutations are detected in all melanoma subtypes. Our study suggests that increases in KIT gene copy numbers, but not KIT mutations, may be correlated to CD117 overexpression. For the first time, our study suggests that genetic KIT aberration is an adverse prognostic factor for melanoma.
