Department of Medical Genetics, University of Calgary, AB, Canada
Hum Genet 108:91-7. 2001..In characterizing transcripts of CACNA1F we have identified several splice variants and defined a prototypical sequence based on the location of mutations in splice variants and comparison with the mouse orthologue, Cacnalf...
- Loss-of-function mutations in a calcium-channel alpha1-subunit gene in Xp11.23 cause incomplete X-linked congenital stationary night blindnessN T Bech-Hansen
Department of Medical Genetics, University of Calgary, Alberta, Canada
Nat Genet 19:264-7. 1998..These findings establish that loss-of-function mutations in CACNA1F cause incomplete CSNB, making this disorder an example of a human channelopathy of the retina...
