R. Sutphen et al., XXY MALE WITH X-LINKED DOMINANT CHONDRODYSPLASIA PUNCTATA (HAPPLE SYNDROME), American journal of medical genetics, 57(3), 1995, pp. 489-492
Happle syndrome is an X-linked dominant disorder with presumed lethali
ty in hemizygous males; familial occurrence is rare. We describe a fam
ily with Happle syndrome affecting individuals in 3 generations. A man
in this family is the first known male patient with Happle syndrome.
He is severely affected; this may be due to his 47, XXY karyotype. (C)
