Terminal deletions of the long arm of chromosome 4 are associated with a recognizable phenotype consisting of dysmorphic facial features, cleft palate, upper and lower limb malformations, cardiac defects and growth and mental retardation. Here we report on two female patients, a mother and her daughter, carrying the same 4q34 → qter deletion but presenting with a different phenotype. The mother's presentation is consistent with previous findings in patients with terminal deletions of the long arm of chromosome 4. However, she presented at the age of 54 years with bilateral serous carcinoma of the Fallopian tubes, a rare gynaecologic cancer that might be attributed to the haploinsufficiency of the tumor suppressor gene FAT. The daughter presented isolated congenital aplasia of the uterus and vagina, the prime feature of the MRKH syndrome. This has not been described before in association with a 46,XX,del(4)(q34qter).
