Poliosis, also called poliosis circumscripta, is the decrease or absence of melanin (or color)
It can give rise to a "Mallen Streak" that can be hereditary.
Symptoms vary from one type of the syndrome to another and from one patient to another, but they include:
Very pale or brilliantly blue eyes, eyes of two different colors (complete heterochromia), or eyes with one iris having two different colours (sectoral heterochromia)[2]
A forelock of white hair (poliosis), or premature graying of the hair
Appearance of wide-set eyes due to a prominent, broad nasal root (dystopia canthorum)—particularly associated with Type I) also known as telecanthus
Moderate to profound hearing loss (higher frequency associated with Type II);[2]
A low hairline and eyebrows that meet in the middle (synophrys)
Patches of white skin pigmentation, in some cases
Abnormalities of the arms, associated with Type III
neurologic manifestations, associated with Type IV
The broad nasal root, is indicative of the PAX6 genetic quirk we are discussing because the PAX6 transcriptor plays a major role in the development of our olfactory bulb. This anatomical anomaly could be the reason for hearing problems, resonance of the cranial cavities.

Take a look at this photo http://archive.is/6TQpB The oldest girl looks like she has greying hair in the front.
