Abstract：
BACKGROUND:The majority of spinal muscular atrophy (SMA) patients showed homozygous deletion or other mutations of SMN1. However, the genetic etiology of a significant number of SMA patients has not been clarified. Recently, mutation in the gene underlying cat SMA, limb expression 1 (LIX1), has been reported. Similarity in clinical and pathological features of cat and human SMA may give an insight into possible similarity of the genetic etiology. PATIENTS AND METHODS:In this study, we screened for a mutation in LIX1 using direct DNA sequencing in our SMA and/or SMA-like patients who retained SMN1. A total of 33 patients were enrolled in this study, of which 22 were Japanese and 11 were Malaysians. All these patients possessed at least two copies of SMN1. RESULTS:We did not identify any pathogenic mutations in the coding regions or splice sites of LIX1 in the patients. In addition, we described a polymorphism within LIX1 intron 3, c.387+107A>T. We found that A-allele is significantly more frequent in SMA patients compared to normal individuals. CONCLUSION:Molecular genetic analysis of our SMA and/or SMA-like patients suggests that LIX1 is not associated with the development of their disorders. However, the number of patients analyzed in this study was very limited, and a larger study with bigger sample size is needed to confirm this result.
