Abstract

We describe the molecular analysis of a large three generation Palestinian family segregating for monilethrix. Previous reports have shown that mutations in type-II hair cortex keratin genes, hHb1 and hHb6, are associated with monilethrix. Genetic linkage analysis performed on this family using markers flanking the hHb6 gene exhibited strong evidence for linkage. Sequence analysis revealed a nucleotide substitution of G → T at nucleotide 1230 resulting in a glutamic acid to aspartic acid amino acid substitution at codon 410, identical to that reported in a French family. The family in our study provides further evidence that mutations of the hHb6 gene are responsible for monilethrix.
