36개월 여아의 퇴행적 발달 지연과 난치성 뇌전증: MECP2 변이 및 레트 증후군(Rett Syndrome)의 임상적 고찰
🎯 핵심 요약 (Key Highlights) 1. Clinical Presentation (Odyssey) 36개월 여아 환자는 초기 운동 발달은 정상적이었으나, 14개월령부터 두위 성장이 둔화(획득성 소두증)되며 언어 및 기득권 손 기능의 급격한 퇴행을 보였습니다. 특히 손을 쥐어짜거나 씻는 듯한 동작(Hand-washing stereotype)이 관찰되었으며, 약물에 반응하지 않는 난치성 뇌전증이 동반되었습니다. 2. HPO Features (표준 용어 기반) 3. Differential Diagnosis (감별 진단) 4.…

Progressive Neurodevelopmental Regression and Refractory Epilepsy in a 36-Month-Old Female: A Clinical Correlation
🎯 [Key Highlights: 3 Takeaways] 1. Patient Presentation 2. Phenotypic Features (HPO-based) 3. Differential Diagnosis (The “Why” for Genetic Testing) Before genetic confirmation, this patient’s symptoms often overlap with: 4. Clinical Insight & Diagnostic Bridge In cases of progressive neurodevelopmental regression, clinical observation alone often fails to distinguish between overlapping monogenic disorders. Early identification of…

Differential Diagnosis of Infantile Hypotonia: A Clinical Guide to Genetic Testing Integration
🎯Key Takeaways for Clinicians Introduction Infantile hypotonia, often referred to as “floppy infant syndrome,” presents a diagnostic challenge for even the most experienced pediatricians and neurologists. With an extensive range of potential etiologies—spanning from central nervous system disorders to peripheral neuromuscular diseases—the path to a definitive diagnosis can be arduous. In an era where early…

Episode 1 – Charcot–Marie–Tooth Disease (CMT): Beyond the Variant
진단명보다 중요한 것 – 기전(mechanism)으로 이해하는 CMT 📌 Series Introduction 이 시리즈는 AI 기반 유전변이 판독 도구가 보편화된 시대에, 자동화된 우선순위화 이후 판독자가 실제로 무엇을 이해하고 어떻게 판단해야 하는지에 초점을 맞춥니다. 각 편에서는 하나의 질환군을 중심으로, 유전적 기전과 임상 스펙트럼을 함께 살펴보며 변이를 “찾는 것”을 넘어 “설명하고 해석하는” 데 필요한 관점을 공유하고자 합니다. Episode 1…

Family Testing: When and Why Is It Necessary?
Why family studies matter after Exome or Genome sequencing 1. From “a variant” to “a diagnosis” Exome and genome sequencing can identify thousands of genetic variants in a single test. However, once results are returned, clinicians and families often face the same fundamental question: “Is this variant truly responsible for my child’s symptoms?” Answering this…
