They included 4 deletion mutations c.644delA (p.Tyr215SerfsX5), c.424delG (p.Val142Leufs*39), c.919del (p.Arg307Glufs*29), and c.395_396delCT (p.Ser132CysfsX18) in genes CLN1, CLN3, CLN5, and CLN6 genes, respectively, which result in frameshift sequencing, cause alteration in the function of each protein, and in turn, result in causing NCL disease [22–24]. This evidence concerns the gene CLN3 and neuronal ceroid lipofuscinosis.
