Inherited defects in nucleotide excision repair are a known cause of what diseasel B) diabetes C)AIDS D) albinism E) heart disea
AleksAgata [21]

Answer:

Inherited defects in nucleotide excision repair are a known case of D) albinism

Explanation:

A defect in one of several genes that produce or distribute melanin causes albinism. The defect may result in the absence of melanin production, or a reduced amount of melanin production. The defective gene passes down from both parents to the child and leads to albinism.Since albinism results in a lack of melanin (or pigment), people with the disorder are sensitive to the sun. The particular gene mutation linked to albinism interferes with the proper development of the nerves associated with the eye as well as the retina itself.

Types of albinism are:

Oculocutaneous albinism (OCA) :

OCA affects the skin, hair, and eyes. There are several subtypes of OCA:  

OCA1

OCA1 is due to a defect in the tyrosinase enzyme. There are two subtypes of OCA1:

OCA1a. People with OCA1a have a complete absence of melanin. This is the pigment that gives skin, eyes, and hair their coloring. People with this subtype have white hair, very pale skin, and light eyes.

OCA1b. People with OCA1b produce some melanin. They have light-colored skin, hair, and eyes. Their coloring may increase as they age.

OCA2

OCA2 is less severe than OCA1. It’s due to a defect in the OCA2 gene that results in reduced melanin production. People with OCA2 are born with light coloring and skin. Their hair may be yellow, blond, or light brown. OCA2 is most common in people of African descent and Native Americans.

OCA3

OCA3 is a defect in the TYRP1 gene. It usually affects people with dark skin, particularly black South Africans. People with OCA3 have reddish-brown skin, reddish hair, and hazel or brown eyes.

OCA4

OCA4 is due to a defect in the SLC45A2 protein. It results in a minimal production of melanin and commonly appears in people of East Asian descent. People with OCA4 have symptoms similar to those in people with OCA2.

Ocular albinism :

Ocular albinism is the result of a gene mutation on the X chromosome and occurs almost exclusively in males. This type of albinism only affects the eyes. People with this type have normal hair, skin, and eye coloring, but have no coloring in the retina (the back of the eye).

Hermansky-Pudlak syndrome :

This syndrome is a rare form of albinism that’s due to a defect in one of eight genes. It produces symptoms similar to OCA. The syndrome occurs with lung, bowel, and bleeding disorders.

Chediak-Higashi syndrome :

Chediak-Higashi syndrome is another rare form of albinism that’s the result of a defect in the LYST gene. It produces symptoms similar to OCA, but may not affect all areas of the skin. Hair is usually brown or blond with a silvery sheen. The skin is usually creamy white to grayish. People with this syndrome have a defect in the white blood cells, increasing their risk of infections.

Griscelli syndrome

Griscelli syndrome is an extremely rare genetic disorder. It’s due to a defect in one of three genes. There only have been 60 known casesTrusted Source of this syndrome worldwide since 1978. It occurs with albinism (but may not affect the entire body), immune problems, and neurological problems. Griscelli syndrome usually results in death within the first decade of life.

Treatment for albinism:

There’s no cure for albinism. However, treatment can relieve symptoms and prevent sun damage. Treatment may include:

sunglasses to protect the eyes from the sun’s ultraviolet (UV) rays

protective clothing and sunscreen to protect the skin from UV rays

prescription eyeglasses to correct vision problems

surgery on the muscles of the eyes to correct abnormal eye movements
