Turner syndrome due to Xp22.33 deletion with preserved gonadal function: Case report

Abstract

Turner syndrome (TS) is a chromosomal condition affecting 1 in 2000 females characterized by partial or complete loss of one of the X chromosomes. We describe an 11-year-old female who was recently diagnosed with TS. Karyotype revealed a deletion of the distal portion of chromosome X. Chromosome single nucleotide polymorphism (SNP) array revealed microdeletion of Xp22.33p22.12. Patient reached her menarche at age 11 years. Both the patient and her mother have short stature. Her mother, however, has a normal karyotype. This is one of few case reports of TS with microdeletion of Xp22.33 reported in the literature, with normal ovarian function and possible future transmission of the deletion to the next generations.
