求翻译：但是不会导致氨基酸替换，已知35C＞T单位点突变在中国已经有报道，不会导致氨基酸编码改变，因此推测748位点的突变导致249位Ala11→Val，是产生类孟买型的原因。是什么意思？

But does not lead to amino acid substitutions known to 35c> t locus mutation has been reported in China, does not result in amino acid coding change, suggesting that the 748 point mutation resulting in 249 ala11 → val, is the Bombay type reasons.

But it does not result in amino acid substitutions, a known C > T unit 35 mutation in China has reported that does not result in amino acid coding changes, and therefore assume that 748 point mutations result in a 249 bit Ala 11 → Val Mumbai, is a type of reason.

But does not cause the amino acid substitution, known 35C>T mutation has been reported in China, does not cause the amino acid coding changes, therefore speculated that 748 point mutations lead to 249-Ala11 → Val, is the cause of Bombay.
