5 OF 7 EPI4K: MULTIPLEX FAMILIES & PAIRS PROJECT
Grant number: 1U01NS077367-01 4U1NS077367-13 | Funding period: 2011 - 2016
DESCRIPTION (provided by applicant): The primary goal of the Epi4K Center Without Walls Is to Increase understanding of the genetic basis of human epilepsy in order to improve the well-being of patients and family members living with these disorders. This improvement will come in the form of better diagnostics, treatments and cures. To accomplish this goal, Epi4K aims to analyze the genomes of a large number of well-phenotyped epilepsy patients and families collected by investigators from several major research groups. The strategy used in this project (5 of 7 - Multiplex Families & Pairs) is to enrich the study sample for genetic influences on epilepsy by studying families containing mu..View full description
