Three novel mutations of CHD7 gene in two turkish patients with charge syndrome; A double point mutation and an insertion.

The CHARGE (coloboma, heart defects, atresia, retardation, genital, ear) syndrome is a genetic disease characterized by ocular coloboma, choanal atresia or stenosis and semicircular canal abnormalities. Most of the patients clinically diagnosed with CHARGE syndrome have mutations in chromodomain helicase DNA-binding protein 7 (CHD7) gene. The CHD7 gene is located on chromosome 8q12.1, and up to now, there are more than 500 pathogenic mutations identified in the literature. We report two patients diagnosed with CHARGE syndrome with two novel mutations in the CHD7 gene: the first patient has double consecutive novel mutations in three adjacent codons, and the other has a novel insertion.

Microcephalic osteodysplastic primordial dwarfism, with the fascinating history of "Mademoiselle Crachami".

This review critically examines the findings which characterize the dysmorphic, radiologic and behavioral phenotype of Microcephalic Osteodysplastic Primordial Dwarfism (MOPD) and has an historical perspective on it. MOPD is a group of primordial dwarfism syndromes with prenatal onset growth retardation, a typical craniofacial appearance and behavioral phenotype. In 1959, Mann and Russell have described the first case in a detailed report, and named "microcephalic midget of extreme type". In their report; based on historical records and a small painting, they pointed "Mademoiselle Crachami" as the oldest known case.
