Type : Other, mainly phenotypes with suspected mendelian basis;
Description : Angioma serpiginosum is an uncommon benign skin disorder characterized by asymptomatic
clusters of nonpurpuric punctate erythematous lesions. The rash is asymptomatic but
may lead to cosmetic problems and can be treated by laser therapy. Women are most
commonly affected, and the disorder is most often sporadic, although rare families
suggestive of autosomal dominant inheritance have been reported (Sandhu and Gupta,
2005). No male-to-male transmission has been described, but father-to-daughter transmissions
are known. It has been suggested that the pattern of skin involvement may be due to
cutaneous somatic mosaicism (Chen et al., 2006; Blinkenberg et al., 2007). An X-linked
dominant form of angioma serpiginosum (300652) has been mapped. The few males described
may actually represent somatic mosaicism of an X-linked gene.;
