Infantile nystagmus syndrome (INS) is a genetically heterogeneous disorder. To date, more than 100 genes have been reported to cause INS and there is significant overlap in phenotypic characteristics. The most common form of X-linked INS is attributed to FRMD7 at Xq26. Recent advances in molecular genetics have facilitated the identification of pathogenic variants of FRMD7 and the investigation for underlying mechanisms of FRMD7-associated INS. This review summarizes genetic and clinical features of FRMD7-associated INS, and introduces updates on the pathogenesis of FRMD7 mutation.
