We describe a four-generation family with fully penetrant, autosomal dominant, congenital cataracts (ADCC), presenting with morphologically homogeneous "zonular pulverulent" cataracts (CZP) and typical early-onset phenotype. Linkage analysis was performed with a panel of polymorphic markers mapped to all genomic regions of ADCC susceptibility. Contiguous(More)
A linkage study of 24 families with hypohidrotic (anhidrotic) ectodermal dysplasia (HED) has been performed. The previously suggested linkage to DXYS1 has been confirmed, and linkage to probes DXS14 and DXS3 has been established. We suggest that the HED locus lies in the centromeric region between DXYS1 on the long arm and DXS14 on the short arm of the X(More)
We report here the second case of Charcot-Marie-Tooth disease 1A (CMT1A) with a cytogenetically visible de novo direct duplication of 17p11.1→17p12. A male child who was initially referred for developmental delay and dysmorphism was subsequently shown to have significantly reduced motor nerve conduction velocities characteristic of CMT1A. This patient was(More)
The Abl tyrosine kinase signaling network controls cell migration, epithelial organization, axon patterning and other aspects of development. Although individual components are known, the relationships among them remain unresolved. We now use FRET measurements of pathway activity, analysis of protein localization and genetic epistasis to dissect the(More)
The early fight-inducible proteins (ELIPs) are nuclear-encoded proteins localized in the chloroplasts and related to cab (light harvesting chlorophyll alb-binffmg) gene family. Light stress controls ELIP expression at different levels, at the level of transcription and the accumulation of the protein in the thylakoid membranes. The induction of ELIP(More)
