Genetic analysis of a large Indian family with an autosomal dominant cataract phenotype allowed us to identify a novel cataract gene, CRYBA4. After a genomewide screen, linkage analysis identified a maximum LOD score of 3.20 (recombination fraction [theta] 0.001) with marker D22S1167 of the beta -crystallin gene cluster on chromosome 22. To date, CRYBA4 was(More)
The anterior-posterior and dorsal-ventral progression of heart organogenesis is well illustrated by the patterning and activity of two members of different families of cell adhesion molecules: the calcium-dependent cadherins, specifically N-cadherin, and the extracellular matrix glycoproteins, fibronectin. N-cadherin by its binding to the intracellular(More)
BACKGROUND Lithium (Li) has been associated with cardiac teratogenicity in the developing fetus. We took advantage of the association of therapeutic administration of Li with an increase in heart defects to gain insight into both normal and pathological heart and valve development with GSK-3 inhibition. The objective of this study was to define whether Li(More)
Members of both Wnt and bone morphogenetic protein (BMP) families of signaling molecules are important in heart development. We previously demonstrated that beta-catenin, a key downstream intermediary of the canonical Wnt signaling pathway, delineates the dorsal boundary of the cardiac compartments in an anteroposterior progression. We hypothesized the(More)
PURPOSE To study some functional candidate genes in cataract families of Indian descent. METHODS Nine Indian families, clinically documented to have congenital/childhood cataracts, were screened for mutations in candidate genes such as CRYG (A-->D), CRYBB2, and GJA8 by PCR analyses and sequencing. Genomic DNA samples of either probands or any(More)
