Cell adhesion and communication are interdependent aspects of cell behavior that are critical for morphogenesis and tissue architecture. In the skin, epidermal adhesion is mediated in part by specialized cell-cell junctions known as desmosomes, which are characterized by the presence of desmosomal cadherins, known as desmogleins and desmocollins. We(More)
Genetic alterations of the FOXN1 transcription factor, selectively expressed in thymic epithelia and skin, are responsible in both mice and humans for the Nude/SCID phenotype. The first described human FOXN1 mutation was a C792T transition in exon 5 resulting in the nonsense mutation R255X, and was detected in two probands originated from a small community(More)

Genotype-phenotype correlations highlighted the function of ABCA4 in retinitis pigmentosa (RP),cone-rod dystrophy (CRD) and Stargardt/Fundus Flavimaculatus disease (STGD/FFM). Initial screening of ABCA4 variants showed a correlation between the type of mutation and the severity of the disease. In the present study we have undertaken mutational and haplotype(More)
Alopecia areata (AA) is a genetically determined, immune-mediated disorder of the hair follicle that affects 1%-2% of the U.S. population. It is defined by a spectrum of severity that ranges from patchy localized hair loss on the scalp to the complete absence of hair everywhere on the body. In an effort to define the genetic basis of AA, we performed a(More)
Multiple cutaneous and uterine leiomyomas is an autosomal dominant condition that results in benign smooth muscle tumours of the skin and, in females, uterine fibroids. This syndrome overlaps with hereditary leiomyomatosis and renal cell cancer syndrome in which affected individuals may develop the rare type II papillary renal cell cancer, in addition to(More)
Striate keratodermas (PPKS) (OMIM 148700) are a rare group of autosomal dominant genodermatoses characterized by palmoplantar keratoderma typified by streaking hyperkeratosis along each finger and extending onto the palm of the hand. We report a four-generation kindred originating from Iran-Syria in which three members were affected with PPKS. Clinically,(More)
Atrichia with papular lesions (APL) is a rare autosomal recessive disorder resulting in complete and irreversible hair loss shortly after birth. Affected individuals also develop papular lesions of keratin-filled follicular cysts over extensive areas of the body. Mutations in the hairless gene, a putative single zinc-finger transcription factor protein,(More)
Cutaneous leiomyomas, rare benign tumors originating from the arrector pili muscle of the hair follicle, can be associated with the common uterine fibroids in a syndrome called multiple cutaneous and uterine leiomyomas. Multiple cutaneous and uterine leiomyomas are inherited as an autosomal dominant trait, providing an excellent opportunity for the study of(More)
Multiple cutaneous and uterine leiomyomata (MCL) is an autosomal dominant disorder characterized by the development of benign smooth muscle tumours (leiomyomas) in the skin and uterus of affected women, and in the skin of affected men. In rare cases, MCL has been associated with a predisposition to the rare type II papillary renal cell cancer, also known as(More)
