Reticulocytes from SCA infants displayed an overall statistically increased expression of the following surface markers: CD239 (Lu/BCAM), CD242 (ICAM-4/LW), CD58 (LFA-3), CD47 (IAP), CD99 (MIC2), CD147 (Basigin) and CD44 (Fig. 1). This evidence concerns the gene CD44 and autosomal dominant cerebellar ataxia.
