Figure Lengend Snippet: Functional analysis of four NPC1 splicing mutations. ( A ) The c.181-2A>G mutation caused the creation of a novel acceptor splice site leading to the insertion of a nucleotide in the mRNA transcript and the alteration of the reading frame; ( B ) the c.3591+121C>T and ( C ) the c.3591+105A>T mutations led to the generation of a cryptic acceptor splice site within intron 23, causing the retention of 119 and 103 nt, respectively, the shifting in the open reading frame, and the generation of a premature stop codon. The abnormal transcript resulting from the presence of c.3591+121C>T mutation was degraded via non-sense mediated decay (NMD). ( D ) In patient NP67, the skipping of exon 14 was observed (r.2131_2245del). The abnormal transcript was degraded via NMD.
