Myopia, or nearsightedness, is a refractive error of the eye. Light rays from a distant object are focused in front of the retina and those from a near object are focused in the retina; therefore distant objects are blurry and near objects are clear (summary by Kaiser et al., 2004).
For a discussion of genetic heterogeneity of susceptibility to myopia, see 160700.
Using a genomewide scan and linkage analysis, Lam et al. (2008) investigated the genetic component of 3 Chinese pedigrees from Hong Kong with autosomal dominant high myopia. They found a maximum 2-point lod score of 4.81 at D5S2505 at theta = 0.00. Haplotype analysis narrowed the linkage region to 5p15.33-p15.2 with a 17.45-cM interval.
