Fig. 2From: Novel biallelic variant in BBS9 causative of Bardet–Biedl syndrome: expanding the spectrum of disease-causing genetic alterationsa Three-dimensional structures of wild-type and altered PTHB1 proteins. b Spectrum of BBS9 pathogenic variants in Bardet–Biedl syndrome. Coding exons are depicted as green boxes, non-coding exons are depicted as white boxes, green arrows indicate variants in coding regions, black arrows indicate splice-site variants and red lines indicate gross deletions (ENST00000242067.11)Back to article page
