Bloch and Sulzberger, in 1926 and 1928, respectively (Bloch 1926; Sulzberger 1928), were credited for the first description of the clinical syndrome of incontinentia pigmenti (IP), known as Bloch–Sulzberger syndrome. It is a rare genodermatoses occurring in approximately 1 in 50,000 newborns (Aradhya et al. 2001).
Synonyms and Related Disorders
Inheritance (Berlin et al. 2002).

Instances of female-to-female transmission

Increased incidence of miscarriages in patients with incontinentia pigmenti, presumably representing affected male conceptuses that typically fail to survive past the second trimester
