This disorder leave incystic fibrosis , sickle cellular phone genus Anemia , and Tay Sachs disease . If a person gets one regular gene and one cistron for the disorder , the individual will be a transporter for the disorder , but typically will not bring out a warning sign . The probability for two carrier parentages to mutually transfer the malfunctioning genetic factor and , as a result , having an altered baby is 25 percent with every pregnancy .
