Multiple congenital ocular anomalies (MCOA) is an inherited eye disorder that is associated with the silver dilution and is characterized by ocular cysts, enlargement of the cornea, abnormally formed iris/retina, and additional abnormalities.
Pre-implantation genetic diagnosis (PGD) is a procedure used to screen embryos recovered after uterine flush to determine sex and genetic traits through DNA testing prior to implantation in the uterus.
Occipitoatlantoaxial malformation (OAAM), an inherited developmental condition primarily found in Arabian horses, causes abnormal development of the vertebrae and results in compression of the upper cervical cord with subsequent neurological damage.
Severe combined immunodeficiency (SCID), an inherited condition primarily affecting Arabians, is characterized by an underdeveloped immune system that results in foals with elevated temperatures, respiratory stress, and diarrhea.
Lavender foal syndrome (LFS) is an inherited lethal coat color dilution found primarily in Arabian horses that is characterized by a dilute lavender, pale pink, or silver coat accompanied by severe neurological abnormalities.
The silver dilution dilutes black/brown pigment to lighten the manes and tails of black and bay horses to a flaxen or silver gray. The silver dilution is also associated with an inherited ocular syndrome known as Multiple Congenital Ocular Anomalies (MCOA).
