Hi Teo,
When I looked at PubMed for Dr Ay Ho I found 20 abstracts from articles where he has been one of the authors. He seems to be one of the best MDS specialists in the world but much of his research is focused on SCT.
Here is a report from 2003 when he was giving a lecture at ASH (the big American conference) together with three very wellknown MDS specialists.

If you can't find a MDS specialist in Malaysia you could contact him.
Kind regards
