Long Arm
Abstract An interstitial deletion of the proximal part of the long arm of the X chromosome was found in two brothers both suffering from choroideremia, congenital deafness and mental retardation. [wwww.unboundmedicine.com]
Results SNP array analysis detected an 8.05 Mb deletion in the long arm of the X chromosome at Xq21.1-21.31 (Fig. 3 ) in both the patient and his mother. [molecularcytogenetics.biomedcentral.com]
This indicates, that there is more than one deafness gene on the proximal long arm of the X-chromosome (Reardon et al. 1991), or alternatively, that allelic mutations cause different phenotypes. [docslide.com.br]

Prognosis
Diagnosis and Prognosis: Choroideremia is usually diagnosed by an ophthalmologist after a dilated eye exam based upon the appearance of the inside of the eye. In cases where the diagnosis is unclear, a genetic analysis can be performed. [disorders.eyes.arizona.edu]
