Hereditary chin trembling: A new family with exclusion of the chromosome 9q13-q21 Locus

Authors


Abstract

Hereditary chin trembling is a rare autosomal dominant condition that has been linked to chromosome 9q13-21 in one kindred. We describe a four-generation family with this condition and, using linkage analysis, have excluded the 9q13-21 region as causing the chin trembling in this family. © 2002 Movement Disorder Society
