Normally, this DNA segment is repeated from 5 to about 40 times. In people with fragile X syndrome, however, the CGG segment is repeated more than 200 times. ]]> 2019-03-27 15:50:55 UTC https://padlet.com/s991001/ms3sgbdhx3fy/wish/345768321 s991001 https://padlet.com/s991001/ms3sgbdhx3fy/wish/345778006 A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. (The Y chromosome is the other sex chromosome.) The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition.]]> 2019-03-27 16:09:34 UTC https://padlet.com/s991001/ms3sgbdhx3fy/wish/345778006 s991001 https://padlet.com/s991001/ms3sgbdhx3fy/wish/360422779 fragile x syndrome occurs in approximately 1 in 4,000 males and 1 in 8,000 females ]]> 2019-05-15 16:14:39 UTC https://padlet.com/s991001/ms3sgbdhx3fy/wish/360422779 s991001 https://padlet.com/s991001/ms3sgbdhx3fy/wish/360851704 fragile x syndrome is a genetic condition that causes a range of development problems including learning disabilities and cognitive impairment ]]> 2019-05-16 15:42:58 UTC https://padlet.com/s991001/ms3sgbdhx3fy/wish/360851704 s991001 https://padlet.com/s991001/ms3sgbdhx3fy/wish/360854887 https://www.cdc.gov/ncbddd/fxs/stories.html]]> 2019-05-16 15:49:18 UTC https://padlet.com/s991001/ms3sgbdhx3fy/wish/360854887
