An equine melanoma is a tumor that results from the abnormal growth of melanocytes in horses. Unlike in humans, melanomas in horses are not thought to be caused by exposure to ultraviolet light. [1] Melanomas are the third most common type of skin cancer in horses, with sarcoids being the first most prevalent and squamous-cell carcinoma being ...
Lethal white syndrome (LWS), also called overo lethal white syndrome (OLWS), lethal white overo (LWO), and overo lethal white foal syndrome (OLWFS), is an autosomal genetic disorder most prevalent in the American Paint Horse.
Gray horses over 6-years-old are especially prone to developing melanoma. [24] The prevalence of melanoma in gray horses over 15 years old [25] has been estimated at 80%. [19] One survey of Camargue-type horses found an overall population prevalence of 31.4%, with prevalence increasing to 67% in horses over 15 years old. [26]
Gray horses with a completely white coat can be distinguished from a white horse by their underlying black skin, particularly around the eyes, muzzle, and genital area. Fleabitten gray Flea-bitten gray is a color consisting of a white hair coat with small pigmented speckles or "freckles".
The Belgian Draft Horse is one breed in which JEB occurs Junctional epidermolysis bullosa ( JEB ) is an inherited disorder that is also known as red foot disease or hairless foal syndrome . [ 1 ] JEB is the result of a genetic mutation that inhibits protein production that is essential for skin adhesion. [ 2 ]
Mushroom on a bay base A mushroom foal with a bay base. The mushroom gene is a recessive dilution gene that affects red pigment in horses. It was identified in 2014. [1]On a chestnut base coat the horse is born a pale beige with sometimes a greyish or pinkish tint and often keeps that color when it becomes an adult, but some turn darker when an adult.
Similarly, horses with a bay base coat and the cream gene will be buckskin or perlino. A black base coat with the cream gene becomes the not-always-recognized smoky black or a smoky cream. Cream horses, even those with blue eyes, are not white horses. Dilution coloring is also not related to any of the white spotting patterns.
Hereditary equine regional dermal asthenia (HERDA), also known as hyperelastosis cutis (HC), is an inherited autosomal recessive connective tissue disorder. It develops from a homozygous recessive mutation that weakens collagen fibers that allow the skin of the animal to stay connected to the rest of the animal.
