Question 66:
Albinism is a genetic disorder associated with:
Albinism primarily affects the skin due to melanin deficiency. The correct answer is (B) Skin.
Option Analysis
Option (A) Heart
Albinism does not impact heart structure or function. It arises from genetic defects in melanin production, with no cardiac involvement.
Option (B) Skin
Albinism is directly associated with skin, causing pale or white coloration, easy sunburn, and higher skin cancer risk from absent melanin protection.
Option (C) Kidney
No connection exists between albinism and kidney disorders. Symptoms center on pigmentation and vision, not renal issues.
Option (D) Urine
Albinism has no effect on urine color or production. Melanin absence affects skin, hair, and eyes only.
Albinism genetic disorder skin effects dominate this inherited condition from melanin production defects, vital for GATE Life Sciences prep. Learn why it’s tied to skin, not heart, kidney, or urine, with symptom breakdowns.
Key Symptoms
-
Pale skin prone to burns and cancer; white/light hair; light-sensitive eyes.
-
Vision problems like nystagmus, photophobia persist lifelong.
Causes & Types
-
Autosomal recessive mutations (e.g., OCA1-4 genes) reduce melanin.
-
Ocular albinism hits eyes mainly; Hermansky-Pudlak adds bleeding risks.
Exam Tips
Correct: (B) Skin—focus on melanin role in pigmentation for MCQs. Protect skin with sunscreen; no cure exists.
