is not always visible at birth; it typically manifests in early infancy, peaks between the ages of 5 and 6, then gradually declines and eventually goes away during puberty.


Causes

Several inheritance patterns with varying penetrance and expressivity have been proposed, such as a familial pattern with either an autosomal dominant or autosomal recessive inheritance. Primary nevoid hypertrichosis and somatic hypertrichosis mosaicism are two other possibilities. There have been some speculative connections made to disorders including the Floating-Harbor syndrome, Wiedemann-Steiner syndrome, and Weill-Marchesani syndrome.
