Rare diseases -- sometimes referred to as orphan diseases -- are medical conditions that affect a small population. The event also marked the official launch of the Thai Rare Disease Foundation. Around 80% of rare diseases are hereditary, meaning it can pass from one generation to the next. There are cases, however, that rare diseases do not exist in family history, but genes can mutate later and bring about sickness. "We also collaborate with related agencies abroad to exchange information and experiences [among families whose children suffer rare diseases]," Preeya added.
