Cytogenetic location: 1p36-p34 Genomic coordinates (GRCh38) : 1:1-46,300,000
For a phenotypic description and a discussion of genetic heterogeneity of susceptibility loci for dyslexia, see DYX1 (127700).
Rabin et al. (1993) reported linkage to RH (111700) on chromosome 1p36-p34 in several families with dyslexia.
Grigorenko et al. (2001) performed linkage analysis of 8 families with dyslexia. Multipoint analysis suggested linkage to chromosome 1p.
Using a qualitative definition of dyslexia in 100 affected Canadian families, Tzenova et al. (2004) identified a dyslexia susceptibility locus, termed DYX8, on chromosome 1p36-p34 (maximum lod score of 3.65 at marker D1S507, distal to D1S199). Quantitative trait locus (QTL) linkage analysis for phonologic awareness, phonologic coding, spelling, and rapid automatized naming speed yielded multipoint lod scores proximal to D1S199 (between D1S552 and D1S1622), with peaks of 4.01 for spelling and 1.65 for phonologic coding.
Among 108 Dutch nuclear families, de Kovel et al. (2008) found linkage for the categorical trait of dyslexia to chromosome 1p36 (nonparametric lod score of 2.1 at D1S199). Scores for the quantitative traits of word reading, nonword reading, and rapid naming peaked near the same location as the categorical trait. Nonword repetition showed little phenotypic correlation with dyslexia or with the other quantitative traits.

Dear OMIM User,
To ensure long-term funding for the OMIM project, we have diversified our revenue stream. We are determined to keep this website freely accessible. Unfortunately, it is not free to produce. Expert curators review the literature and organize it to facilitate your work. Over 90% of the OMIM's operating expenses go to salary support for MD and PhD science writers and biocurators. Please join your colleagues by making a donation now and again in the future. Donations are an important component of our efforts to ensure long-term funding to provide you the information that you need at your fingertips.
Thank you in advance for your generous support,
