BoardCore Prep · Question 21 of 50
Liver / Hepatology PG-0021 · Hard
A 4-year-old presents with progressive jaundice, pruritus, and xanthomas. Liver biopsy shows paucity of intrahepatic bile ducts. Ophthalmology reveals posterior embryotoxon. Echocardiogram shows peripheral pulmonary stenosis. Which gene mutation is responsible?
AATP8B1 / FIC1 deficiency (PFIC type 1)
BJAG1 / Alagille syndrome
CABCB11 / PFIC type 2 (BSEP deficiency)
DSERPINA1 / Alpha-1 antitrypsin deficiency
The triad of cholestasis + posterior embryotoxon + peripheral pulmonary stenosis is pathognomonic for Alagille syndrome. JAG1 encodes a Notch ligand; mutations disrupt bile duct morphogenesis. Biopsy: <0.5 bile ducts per portal tract.
Alagille syndrome = JAG1 mutation + ≥3 of 5 features: cholestatic liver disease, cardiac defect (peripheral PS), posterior embryotoxon, butterfly vertebrae, characteristic facies. GGT markedly elevated, which distinguishes from low-GGT PFIC.
NASPGHAN/ESPGHAN 2023: JAG1 (or NOTCH2) mutation + ≥3 major criteria = diagnostic without biopsy. Annual surveillance: liver function, echo, ophthalmology, renal ultrasound. Cardiac anatomy is key pre-transplant variable.
A (FIC1/ATP8B1): PFIC1: low GGT cholestasis, no cardiac/ocular features.
C (BSEP/ABCB11): PFIC2: severe pruritus, very low GGT, no systemic findings.
D (SERPINA1): PAS+ globules on biopsy; no Alagille features.

The Platform

Three tools. One system.

Built for one purpose: passing your boards efficiently, not just practicing more.

📋
Study Mode
Filter by domain, set your session length, and work through cases at your pace. Every question includes a four-layer explanation that builds real understanding, not just pattern matching.
→9 domains: Liver, IBD, Motility, Nutrition, Pancreas & more
→Clinical Reasoning · Bottom Line · Guideline · Why Others Wrong
→Flag questions; track per-session accuracy
⏱
Mock Exam Mode
Choose your length: 5, 10, or 25 questions. No pausing, no hints. A color-coded timer trains you to manage pace before exam day, not just knowledge.
→Full timed simulation: amber at 10 min, red at 5 min
→Navigation map: flag and jump to any question
→Domain-by-domain breakdown on completion
✦
AI Coach New
After 10 questions, your AI Coach looks at everything you've answered and shows you where your gaps are. One tap starts a focused session on your weak spots.
→Looks past scores and finds the actual pattern behind your wrong answers
→Tells you which domain and why, not just a score
→Works for both fellows and MOC attendings
Workflow

From first login to targeted study in four steps.

Answer Cases
Work through Study Mode or Mock Exam. Every answer, right or wrong, is tracked.
2
Build Your Map
A live performance profile builds across all 9 domains as you go. It builds itself.
3
Run AI Analysis
After 10 questions, launch your AI Coach. It tells you exactly where you're weak and what to do about it.

Not a score.
A strategy.

Most question banks show you what you got wrong. BoardCore Prep tells you why you keep getting it wrong and points you to what needs work.

After 10+ questions, your AI Coach looks at your full history and tells you exactly where your gaps are, in clinical terms that make sense for a physician.

⟁
Domain precision: not "study more liver." Specific gaps: cholestasis pathways, metabolic disease, portal hypertension mechanisms.
↻
Pattern detection: finds recurring errors across multiple questions on the same topic.
▶
One-tap sessions: the recommended study session loads instantly. No filtering, no setup.
⊕
MOC-aware: the depth shifts depending on whether you're a fellow or an attending going for recertification.

What Users Are Saying

What physicians are saying.

"

Didn't expect much honestly, but the AI coach caught something I kept missing. Kept getting cholestasis questions wrong for the same reason and didn't even realize it. That alone was worth it.

I've done MOC prep with the usual stuff and this actually made more things stick. Walking through why the wrong answers are wrong is what does it for me, not just seeing the right one highlighted.

Most qbanks feel like they were written by someone who read a textbook. The IBD and motility questions here actually reflect how attendings think about these cases. Big difference.

Each question includes four explanation layers and an AI Coach that tells you exactly where to focus. You practice, get real feedback, and study what you actually need to, not just what you already know.
How many questions are available right now?
The platform currently includes 150 board-style questions across all 12 Pediatric GI domains. We're expanding toward 200+ questions, with new content added regularly. All subscribers get access to every new question as it's added.
Who wrote the questions?
Every question, explanation, and clinical rationale was written and reviewed by board-certified practicing Pediatric GI physicians, grounded in current societal guidelines and best available evidence, reflecting the clinical reasoning patterns tested on the actual board exam.
How does the AI Coach work?
After 10+ questions, the AI Coach (powered by Claude AI from Anthropic) looks at everything you've answered across all 9 domains and shows you where your gaps are. One tap starts a focused session on your weak spots. Your results stay saved until you run a new analysis.
