Neonatal cyanosis can result from a multitude of acquired and inherited causes. Cyanosis resulting from fetal M hemoglobin (Hb) variants is very rare. Only two (G)gamma variants causing methemoglobinemia and cyanosis in the newborn have been reported to date. Here we describe a novel fetal Hb variant, Hb F-Circleville [Ggamma63(E7)His-->Leu], associated with methemoglobinemia and cyanosis in the newborn. The patient's sister also had neonatal cyanosis at birth.
新生儿发绀可由多种后天性和遗传性原因引起。胎儿高铁血红蛋白（Hb）变异导致的发绀非常罕见。迄今为止，仅报道了两种导致新生儿高铁血红蛋白血症和发绀的（G）γ变异体。在此，我们描述一种新的胎儿Hb变异体，即Hb F- Circleville [Gγ63（E7）His→Leu]，它与新生儿高铁血红蛋白血症和发绀有关。该患者的妹妹出生时也有新生儿发绀。
