What is the difference between albinism & vitiligo??


Albinism:--It is a genrtic disorder and the defective gene sharing is not uncommon in consanguineous marriages. In consang.marriages defective gene which presumably passed down from both parents to the child and ahs lead to albinism of the neonate. Different gene defects characterize the numerous types of albinism. By contrast Vitiligo is more common than albinism. Almost about 1 percent of the world’s population has vitiligo. In this condition, the cells that are responsible for  skin color are destroyed. Melanocytes cells, , no longer produce skin pigment, called melanin. So, areas of skin will lose color or turn white. Areas of lost pigment can develop anywhere in body, including: sun-exposed areas like the hands, feet, arms, and face inside the mouth or other mucus membranes, nostrils, genitals, back of the eye,  within the hearing system of the ears. t’s unknown exactly what causes vitiligo. The condition doesn’t appear to be inherited. Most people with vitiligo don’t have a family history of the disorder. But family history of vitiligo or other autoimmune conditions may increase your risk even though it doesn’t cause vitiligo.Another risk factor may be having genes associated with vitiligo, including NLRP1 and PTPN22
Most researchers believe that vitiligo is an autoimmune disorder because your body is attacking your own cells. But it’s also unclear how your body attacks your pigment cells. What is known is that about 20 percentTrusted Source of people with vitiligo also have one other autoimmune disorder. Depending on the population, these disorders can include the following, from most common to least common:
scleroderma, a disorder of the connective tissue of the body
lupus
thyroiditis, caused by an improperly functioning thyroid
psoriasis
alopecia areata, or baldness
type 1 diabetes
pernicious anemia, an inability to absorb vitamin B-12
Addison’s disease
rheumatoid arthritis
Some experts also report vitiligo appearing after incidents of:
severe sunburns or cuts
exposure to toxins and chemicals
high levels of stress
