CLCC1 and autosomal recessive retinitis pigmentosa: Li et al. (Li et al., 2018) previously identified the homozygous missense alteration (c.75C > A, p. D25E) in CLCC1 associated with autosomal recessive retinitis pigmentosa (arRP) in eight consanguineous families of Pakistani descent that were suggested to originate from a common founder on the basis of sharing a common SNP haplotype in the CLCC1 gene region.
