, Q1. A researcher is studying a signaling pathway where a ligand binds to a receptor
tyrosine kinase, leading to activation of RAS. Which mutation would most likely
result in constitutive activation of the pathway, independent of ligand binding?
A. A loss-of-function mutation in the GTPase-activating protein (GAP) that inactivates
RAS
B. A gain-of-function mutation in the SH2 domain of the receptor that prevents binding
of Grb2
C. A mutation that enhances the intrinsic GTPase activity of RAS
D. A mutation that prevents dimerization of the receptor tyrosine kinase
Correct Answer: A. A loss-of-function mutation in the GTPase-activating protein
(GAP) that inactivates RAS
Rationale: RAS is active when bound to GTP and inactive when bound to GDP. GAPs
accelerate GTP hydrolysis, turning RAS off. Loss of GAP function leaves RAS in the active
GTP-bound state, causing constitutive signaling. The other options would reduce or block
pathway activation.
Why Wrong:
B - Preventing Grb2 binding would disrupt the link between receptor and RAS,
reducing activation.
C - Enhanced GTPase activity would rapidly inactivate RAS, not constitutively
activate it.
D - Preventing dimerization would block receptor activation and downstream
signaling.

Disease, 10th Ed., Ch. 3.
Q2. A patient presents with fatigue, weight gain, cold intolerance, and constipation.
Labs show elevated TSH and low free T4. Which pathophysiologic mechanism best
explains these findings?
A. Autoantibodies that stimulate the TSH receptor
B. Destruction of the anterior pituitary gland
C. Autoimmune destruction of the thyroid gland with reduced negative feedback
D. Peripheral resistance to thyroid hormone at the nuclear receptor
Correct Answer: C. Autoimmune destruction of the thyroid gland with reduced
negative feedback
Rationale: Elevated TSH with low free T4 indicates primary hypothyroidism due to thyroid
failure. Autoimmune destruction (e.g., Hashimoto's thyroiditis) reduces thyroid hormone
production, decreasing negative feedback on the pituitary, thus increasing TSH. The other
options cause hyperthyroidism or central hypothyroidism.
