The LEP gene codes for an anorexigenic hormone. Interestingly, breastfeeding has been shown to alter methylation of the promoter of this gene, leading to increased LEP expression. What is likely happening in response to breastfeeding? - Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes. A patient with xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because of a mutation in...

AMCB 6 Exam Questions with Correct Answers Xeroderma pigmentosum (XP) - Answer-Rare autosomal recessive disease Extreme sensitivity to UV light People with XP have defective nucleotide excision repair pathways Cockayne Syndrome - Answer--Another DNA repair deficiency like XP -Characterized by photosensitivity, premature aging, neurological symptoms, and early death -Defect in transcription-coupled repair -Said to arise from RNA pol molecules permanently stalled at sites of DNA damage ...

Adenosine deaminase (ADA) deficiency - AnswerAn immunodeficiency disorder and one type of SCIDs that is caused by an *inborn error in the metabolism of adenine*. The accumulation of adenine destroys both B and T lymphocytes. Increase in dATP is lymphotoxic Lesch-Nyhan syndrome - Answer*Defective purine salvage due to absent HGPRT*, which converts hypoxanthine to IMP and guanine to GMP. Results in *excess uric acid production and de novo purine synthesis*. X-linked recessive Findings...
