OMIA 001311-9615 : Photoreceptor dysplasia in Canis lupus familiaris |
Mendelian trait/disorder:
yes
Mode of inheritance:
Autosomal Recessive
Considered a defect:
yes
Key variant known:
no
Species-specific description:
Zhang et al. (1998) showed that some Miniature Schnauzers with this disorder are homozygous for a missense mutation in codon 82 (CGA -> GGA) of the gene for phosducin, creating an amino acid substiturion of Arg -> Gly. However, since some affected dogs are heterozygous for this mutation, and other affecteds are homozygous for the normal allele, it remains an open question as to whether this mutation has anything to do with the disorder.
Breed:
Miniature Schnauzer.
