First, the birth weight of children from psoriatics is influenced by the sex of the psoriatic parent. Children from fathers with psoriasis are considerably (270 g) heavier than children from mothers with psoriasis (<jats:italic>P<\/jats:italic>&lt;0.004). Second, the disease manifestation (penetrance) depends in part on the sex of the psoriatic parent. Offspring from fathers with psoriasis and male \u201cgene carriers\u201d are significantly (<jats:italic>P<\/jats:italic>&lt;0.015 and <jats:italic>P<\/jats:italic>&lt;0.007) more often affected than offspring from mothers with psoriasis and female \u201cgene carriers.\u201d Of 91 grandchildren with psoriasis 59 (65%) have an affected grandfather and 32 (35%) a psoriatic grandmother. This deviation from the expected distribution is significant (<jats:italic>P<\/jats:italic>&lt;0.04). Genomic imprinting is considered a special case of epigenetic modification. We propose that epigenetic modification. of a major predisposing gene in somatic tissues could cause differences in disease activity of psoriasis and could account for the often unpredictable clinical course the disease takes.<\/jats:p>","DOI":"10.1002\/ajmg.1320420504","type":"journal-article","created":{"date-parts":[[2005,6,12]],"date-time":"2005-06-12T03:51:11Z","timestamp":1118548271000},"page":"649-654","source":"Crossref","is-referenced-by-count":45,"title":["Psoriasis vulgaris, fetal growth, and genomic imprinting"],"prefix":"10.1002","volume":"42","author":[{"given":"Heiko","family":"Traupe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Petra J.
