The Physicians obey seven rules to refuse treatment; no treatment for the arrogant and unreasonable; no treatment for the light-minded covetous; no treatment for those incapable of providing themselves with food and clothing; no treatment for those whose vital energy is unsteady; no treatment for those born with abnormalities; no treatment for those who believe in martial arts but disdain medicine; and lastly, physicians do not treat themselves.
These are the Seven Prohibitions of the physician, also known as the seven "Do not treat".
Setting aside the others, in the era of the great clans, there were always some cases of incestuous relationships and no family was exempt.
Children born of such unions are often regarded as different.
The term "different" did not refer to being exceptional, but it's a generic term used by physicians for such patients.
