If my twin brother has hemophilia but I don't, what are the chances that my kids will develop it?

If my twin brother has hemophilia but I don't, what are the chances that my kids will develop it?

Depends on sex: If the unaffected twin is male he would not carry the gene and could not pass it on to his children. If the unaffected twin was female she could be a carrier and could pass the gene on to her children. If she did her male children would be affected and her female children would be carriers. ...Read more

My twin brother (16) is 3 in. Taller than me, is my height stunted or should I expect a growth spurt?

My twin brother (16) is 3 in. Taller than me, is my height stunted or should I expect a growth spurt?

Maybe,maybe not: Most twins are fraternal, they come from different eggs and contain different dna profiles.Your rate of growth may well be different and your eventual height may also. An xray of your hand can be analysed to see if you have more growth coming. If your bone maturity is like most 16 yo you have some growth coming but 3 inches would be a stretch.If the bones were more like a 14 yo you might catch up. ...Read more

I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?

I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?

Minimal: These odd micro-deletion syndromes are thought to arise as new defects which could be dominantly passed. Unless you carry it, you won't pass it to your kids and they would have the same risk as the general population to acquire it (new). You might benefit from discussing any and all genetic risk issues from both sides of the family with a geneticist. ...Read more

Why does hip fall out of socket? My twin brother is disabled because of his back. About ten days ago he ended up in emergency room and the doctors found his hip was out of place. They popped it back into place and he was released. Before he got home it

Why does hip fall out of socket? My twin brother is disabled because of his back.  About ten days ago he ended up in emergency room and the doctors found his hip was out of place.  They popped it back into place and he was released.  Before he got home it

Hip : Hip dislocation is relatively unusual because the hip is typically a stable, so-called ball & socket joint. It has to be, so that we can walk and stand stably. The hip joint may be dislcoated traumatically (such as after a car accident in which knee hits dashboard and thigh and hip are driven out back of joint. This often occurs with a break in the back portion of the hip socket, which makes it less stable. Some babies are born or develop with underformed hip sockets (they are more dishes than deep cups) and the hip may dislocated because of the lack orf surrounding bony support. Folks with total hip joints may also dislocate if the patient moves into a position that can lever the prostheis out of the joint or if the joint was either put in incorrectly or if the prosthesis wore down to the point of it no longer being unstable. It sounds like your brother has a neurologic impairment that causes muscular imbalance that causes uneven pull around the hip joint that favors pulling the joint out of place. This may be a difficult situation to manage. Once dislocated, it may have the propensity to dislocate more easily (i think you've seen this already). It sounds like the belt (or brace) may not have done it's intended job. Sometimes either the hip socket or the ball (head) of the femur must be re-oriented to help to provide stability. The longer this remains out of joint, the more difficult it may be to put this back into it's correct position. An orthopaedic surgeon who specializes in such neurologic problems should be able to help. Pediatric orthopaedic surgeons often treat children with similar neuromuscular imbalances and some will treat adults with similar problems, while others will not but may know of local orthopaedic surgeons (who may have an interest in the hip joint or hip replacement) who will. Good luck! ...Read more
