Assessing actin-pathway interactions in variants identified in patients with ocular coloboma


ABSTRACT: We used whole exome sequence to identify de novo mutations in patients with ocular coloboma. Three of these encoded actin pathway components, ACTG1, TWF1 and LCP1. Mass spectrometry-based interactomes of wild-type and mutant proteins were performed to reveal altered functional interactions for all three variants.

Ocular coloboma (OC) is a defect in optic fissure closure and is a common cause of severe congenital visual impairment. Bilateral OC is primarily genetically determined and shows marked locus heterogeneity. Whole-exome sequencing (WES) was used to analyze 12 trios (child affected with OC and both unaffected parents). This identified de novo mutations in 10 different genes in eight probands. Three of these genes encoded proteins associated with actin cytoskeleton dynamics: ACTG1, TWF1, and LCP1.  ...[more]
