Compared with that of the control group,the positive rate of CD29 and CD44 of MPC of antibody group had significant difference (P

Usher syndrome (USH) is the most common syndromic retinitis pigmentosa (RP),which is an autosomal recessive disorder.RP is highly clinically and genetically heterogeneous.A total of 12 loci including nine genes have been identifiedas causing various clinical subtypes of USH.The USH2A gene is thought to be involved in the pathogenesis of most USH2 cases.Moreover,mutations of the USH2A gene is also responsible for atypical USH and nonsyndromic retinitis pigmentosa.Some studies found that the mutation spectrum among Chinese RP patients might differ from European Caucasians.Herein,the further survey should be performed to ascertain the hot gene mutation spectrum.

Sanger sequencing technology is the most commonly used method for genetic analysis in inherited eye disease in the past few decades on account of its long DNA sequencing read length and high accuracy.However,application of this method is limited in genetically heterogeneous diseases because of the high economic and time cost.Next generation sequencing (NGS) technology is a high-throughput,cost-effective,and highly automated method which has been widely used since 2005.Although NGS is especially suitable for studies on genetically heterogeneous inherited eye disease,overdependence on the technique itself and neglect of the assessment of the phenotype may lead to misjudgment of the testing results and higher economic burden for the patients.So far,the most common method on researches of monogenic inherited eye disease is to combine NGS and Sanger sequencing technique.Precise evaluation of the clinical phenotype of patients is very important,as it is related with selection of detection methods and determination of disease-causing mutations.
