								| HC – HEREDITARY CATARACTS. 
 It is known that HC is inherited 
												by and automal recessive path 
												(i.e. both parents must be 
												carriers of the defective gene 
												to produce and affected 
												offspring). HC is a progressive 
												condition and this means that 
												although a puppy is not born 
												with cataracts they will start 
												to develop at a juvenile age. 
												(maybe from 8 months onwards), 
												and will progress until the dog 
												is totally blind. This condition 
												is bilateral which means is 
												affects both eyes equally. 
												Thanks to the tireless research 
												by the Animal Health Trust in 
												Newmarket there is a now a DNA 
												Test for Hereditary Cataracts.
