Rationale for change
Unfortunately, no approved source for the name change because this is pretty LY - Klein Waardenburg is a subtype of Waardenburg in general. PAX3 mutations contribute to multiple disease subtypes (both Type 1 and Type 3)
Also edited card to focus on more HY topics - AMBOSS question directly asks about the cause of the syndrome, answer is impaired development of neural crest cells
