Primary Autosomal Recessive Microcephaly: Homozygosity Mapping of MCPH4 to Chromosome 15

Molecular and Cellular Basis of Autosomal Recessive Primary Microcephaly

Autosomal recessive primary microcephaly (MCPH) is a rare hereditary neurodevelopmental disorder characterized by a marked reduction in brain size and intellectual disability. MCPH is genetically heterogeneous and can exhibit additional clinical features that overlap with related disorders including Seckel syndrome, Meier-Gorlin syndrome, and microcephalic osteodysplastic dwarfism. In this revi...

Phenotype of autosomal recessive congenital microphthalmia mapping to chromosome 14q32.

BACKGROUND Congenital microphthalmia (OMIM: 309700) may occur in isolation or in association with a variety of systemic malformations. Isolated microphthalmia may be inherited as an autosomal dominant, an autosomal recessive, or an X linked trait. METHODS Based on a whole genome linkage analysis, in a six generation consanguineous family with autosomal recessive inheritance, the first locus f...

Microcephaly-cardiomyopathy: a new autosomal recessive phenotype?

A distinctive phenotype of severe microcephaly and self-limiting dilated cardiomyopathy has been observed in two sibs suggesting autosomal recessive inheritance. Mental retardation, delayed developmental milestones, and minor dysmorphism were additional features.

A novel locus for autosomal recessive primary microcephaly (MCPH6) maps to 13q12.2.
