Synopsis

There is a familial variant of glomus tumor, linked to chromosome 1p21–22, encoding the glomulin gene (GLMN). Multiple glomus tumors are inherited as an autosomal dominant trait and are usually found on the legs. They are often present in younger children. Neurofibromatosis type 1 may present with numerous glomus tumors involving the digits. They are often painless.
