Translocations between the Y chromosome and an autosome are rare. We report a phenotypic male with a translocation between the Y chromosome and chromosome 6p, leading to partial 6p monosomy and XX male syndrome. He is the second child to be reported with this karyotype. Phenotypic findings included growth retardation, severe developmental delay, a Dandy-Walker malformation, cardiac and urogenital abnormalities, bilateral hearing loss, cleft palate, severe kyphoscoliosis, minor digital anomalies, and a hypoplastic phallus. Craniofacial dysmorphism consisted of dolichocephaly, hypertelorism, down-slanting palpebral fissures, depressed nasal bridge and a tented upper lip. Cytogenetic analysis showed the karyotype 46,XX,der(6)t(Y;6)(p11.2;p23).ish der(6)(SRY+,6pTEL48-). The effects of partial monosomy 6p are discussed and compared to other patients with interstitial and terminal 6p deletions.
