About 10 percent of people with cri-du-chat syndrome inherit the chromosome abnormality from an unaffected parent. In these cases, the parent carries a chromosomal rearrangement called a balanced translocation, in which no genetic material is gained or lost.ost cases of cri-du-chat syndrome are not inherited. The deletion occurs most often as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Affected people typically have no history of the disorder in their family.

4. Check your motherboard's documentation to see how much RAM it can support. Beyond the number of physical modules your motherboard can fit, there is typically a limit to the amount of memory your motherboard will support in gigabytes (GB) .1  Your operating system may also put a limit on how much RAM can be used. You must use the type that your motherboard supports. 2  RAM is measured by two different numbers: the PC/PC2/PC3 number and the MHz speed. 3  The PC number (ex. 4  PC3 10600) refers to the maximum bandwidth, or maximum amount of data that can be transferred at once (e.g. 10600 = 10.6 GB maximum bandwidth).
