Acral Mutilation Syndrome (AMS)

Acral Mutilation Syndrome (AMS)   Gene: GDNF-AS Transmission: Autosomal recessive For an autosomal recessive genetic disease an animal must have two copies of the mutation in question to be at risk of developing the disease.  Both parents of an affected animal must be carriers of at least one copy of the mutation.  Animals that have…

Chondrodystrophy, CDDY/ Intervertebral Disc Disease, IVDD

Chondrodystrophy, CDDY/ Intervertebral Disc Disease, IVDD (Hansen’s Type 1)   Gene: FGF4 retrogene Transmission: Autosomal dominant for Intervertebral Disc Disease (IVDD), autosomal semi-dominant for Chondrodystrophy (CDDY), or short legs. Note that the genetics of these phenotypes is complex, and although the FGF4 retrogene is known to be implicated, it is not presumed to be the…
