Phenotypic variations in X chromosome mutations: Two case reports

We present two cases of partial X chromosome deletions that do not reflect the typical phenotype of TS.Patient 1 presented at age 17 with primary amenorrhea, cognitive delay and tall stature. Patient 2 presented at age 16 with primary amenorrhea, normal intelligence and average stature.Patient 1's karyotype revealed isodicentric X chromosome [46 X, idic(X)(q21)]. Patient 2's karyotype revealed [46 X,del(X)(q13.3)]. The stature of these patients was not affected. Estrogen therapy was required to provide secondary sexual changes promote bone health.Advances in technology and reproductive health provide an opportunity to make more specific recommendations for patients previously mistakenly diagnosed with TS.
