In 1995, the gene implicated in XLOA (OA1) was cloned.1 So far, we have found mutations in the OA1 gene in only 15% of the X linked ocular albinism patients (unpublished). Also Schiaffinio et al 2 revealed mutations in only one third of XLOA patients. Here, we report on the clinical features of a person with XLOA in which the entire OA1 gene was missing due to a submicroscopic interstitial deletion in the distal short arm of the X chromosome. The detailed molecular findings were published elsewhere.3 As Winship et al 4 suggested that XLOA and late … ER -
