Exome technology makes it possible to sequence all exons in the genome. The exon is the part of the gene that is translated into proteins. Leukodystrophies are a group of genetic diseases that affect white matter and primarily its major component, myelin. Despite advances in gene identification, 60% of patients remain without any genetic abnormalities found. We performed exome sequencing in a cohort of 80 patients with leukodystrophies of undetermined cause.<\/p>\n<p>We have identified the causal mutation in 56% of cases, the remaining 44% are being analyzed with several candidate variants. This analysis allowed us to divide our cohort into three subgroups. A group with mutations in known genes for leukodystrophies (15%), a 2nd group with mutations in genes already involved in another genetic disease and with a very atypical clinical picture (9%), and a 3rd group with mutations in potentially candidate genes (32%).<\/p>\n<p>The identification of mutations in known leukodystrophy genes by exome sequencing has demonstrated the major interest in developing a chip that brings together all known leukodystrophy genes for diagnostic application.<\/p>\n            <\/div>\n            <\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"template":"","news_research_categories":[126],"news_research_tags":[],"class_list":["post-20246","news_research","type-news_research","status-publish","hentry","news_research_categories-clinical-trial"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 -
