FGFR3 관련 연골이형성증(연골무형성증 및 관련 질환)
- FGFR3 관련 연골이형성증상염색체 우성
기능 획득(gain-of-function) FGFR3 변이로 발생하는 골격 이형성증입니다. 대부분은 부모로부터 유전되기보다 새로 발생한(de novo) 경우이며, 거의 모든 연골무형성증은 단일 변이인 p.Gly380Arg로 인해 발생합니다.
- ClinGen의 이 연관성 평가: 확정적
- 6명의 GenCC 제출자가 확정적 또는 강함으로 평가합니다
알면 달라지는 점
전문의의 추적 관찰을 통해 두개골 기저부와 척추의 협착 같은 합병증을 모니터링하며, 연골무형성증 아동의 성장을 개선하기 위해 vosoritide가 승인되어 있습니다.
증후군성 두개골유합증
조기 두개골 봉합선 폐쇄와 함께 다른 특징이 나타나는 질환으로, Apert, Crouzon, Pfeiffer, Muenke, Saethre-Chotzen 증후군이 포함되며 FGFR2, FGFR3, FGFR1, TWIST1, TCF12, ERF 등의 유전자에 의해 발생합니다.
- ClinGen의 이 연관성 평가: 확정적
- 6명의 GenCC 제출자가 확정적 또는 강함으로 평가합니다
알면 달라지는 점
조기에 진단받으면 적시에 수술을 받고 머리 성장, 시력 및 청력을 지속적으로 관찰할 수 있습니다. Muenke 증후군과 같은 경미한 형태는 성인이 되어서도 알아차리지 못할 수 있으며, 이는 가족계획과 관련이 있습니다.
유전 양식
- 상염색체 우성
- 어느 부모에게서 물려받든 변화된 사본 하나면 충분합니다. 이 변이를 가진 부모는 자녀 각각에게 2분의 1 확률로 이를 물려줍니다.
