Previous studies have suggested mostly quantitative susceptibility loci for dyslexia on chromosomes 1, 2, 6, and 15, but no genes have been identified yet. We studied a large pedigree, ascertained from 140 families considered, segregating pronounced dyslexia in an autosomal dominant fashion. Affected status and the subtype of dyslexia were determined by neuropsychological tests. A genome scan with 320 markers showed a novel dominant locus linked to dyslexia in the pericentromeric region of chromosome 3 with a multipoint lod score of 3.84. Nineteen out of 21 affected pedigree members shared this region identical by descent (corrected p&lt;0.001). Previously implicated genomic regions showed no evidence for linkage. Sequencing of two positional candidate genes, <jats:italic>5HT1F<\/jats:italic> and<jats:italic>DRD3<\/jats:italic>, did not support their role in dyslexia. The new locus on chromosome 3 is associated with deficits in all three essential components involved in the reading process, namely phonological awareness, rapid naming, and verbal short term memory.<\/jats:p>","DOI":"10.1136\/jmg.38.10.658","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T06:30:44Z","timestamp":1027751444000},"page":"658-664","source":"Crossref","is-referenced-by-count":125,"title":["A dominant gene for developmental dyslexia on chromosome 3"],"prefix":"10.1136","volume":"38","author":[{"given":"Jaana","family":"Nopola-Hemmi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birgitta","family":"Myllyluoma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuomas","family":"Haltia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikko","family":"Taipale","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vesa","family":"Ollikainen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timo","family":"Ahonen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arja","family":"Voutilainen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juha","family":"Kere","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"Wid\u00e9n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2001,10,1]]},"reference":[{"key":"2025101714540770000_38.10.658.1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1007\/BF02656900","article-title":"Defining dyslexia as a developmental language disorder.","volume":"39","author":"Catts","year":"1989","journal-title":"Ann Dyslexia"},{"key":"2025101714540770000_38.10.658.2","doi-asserted-by":"crossref","first-page":"143","DOI":"10.1007\/BF02648083","article-title":"Spelling errors and reading fluency in compensated adult dyslexics.","volume":"41","author":"Lefly","year":"1991","journal-title":"Ann Dyslexia"},{"key":"2025101714540770000_38.10.658.3","doi-asserted-by":"crossref","unstructured":"Lyytinen H Leinonen S Nikula M Aro M Leiwo M (1995) In search of the core features of dyslexia: observations concerning dyslexia in the highly orthographically regular Finnish language. in The varieties of orthographic knowledge.
