49,XXXXY syndrome is a rare sex chromosome aneuploidy and characterized by mental retardation, skeletal defects, craniofacial anomalies and hypogonadism. The increased frequency of diabetes mellitus in patients with Klinefelter syndrome and other types of X-chromosome polysomy has been reported, but no cases of diabetes mellitus in adult with 49,XXXXY syndrome have been reported so far. We report an 18-year-old patient with 49,XXXXY syndrome accompanying diabetes mellitus.

49,XXXXY syndrome is a very rare sex chromosomes polysomy, which is always connected with dysmorphic appearance, hypergonadothrophic hypogonadism and mental retardation. In this report we describe the clinical, biochemical, hormonal, radiological and developmental status of the patient with 49,XXXXY syndrome, referred to our department at the age of 12 months because of underdeveloped external genitalia. Subclinical hypothyroidism and severe scoliosis could further disturb his development.

49,XXXXY is a rare sex chromosome polysomy with an incidence of 1 in 85 000 male births. It has a characteristic triad of mental retardation, skeletal malformation and hypogonadism. This is the first case report of a child with 49,XXXXY syndrome and renal agenesis. This child was referred for genetic testing at 14 years of age due to facial dysmorphism and hypergonadotropic hypogonadism. He had coarse facial features, cryptorchidism of the right testis, genu valgus deformities, and patent ductus arteriosus which are known associations of 49,XXXXY syndrome. He also had agenesis of the right kidney, hydronephrosis of the left kidney with hydroureter which is not a known association of 49,XXXXY syndrome. The patient was the offspring of a mother with gestational diabetes. There is a strong correlation between maternal diabetes and congenital anomalies, especially renal and cardiovascular anomalies. Additionally, it has been noted that gestational diabetes increases the incidence of chromosomal aneuploidies. The teratogenic effects of maternal diabetes during embryogenesis may be the causative factor for the final phenotype of 49,XXXXY syndrome and renal agenesis.
