Why was the GP examining the pulses and cardiovascular system?

Turner's Syndrome

is usually caused by the absence of the whole or part of one X chromosome (XO) but can result from a mosaic genotype (15%) e.g. 45 X/46 XX or 45X/47 XXX.

Classic Features include:

Short stature, gonadal dysdenesis, lymphoedema, neck webbing, high palate, broad chest, wide carrying angle, hypoplastic and widely spaced nipples. 15-30% of Turner's patients have co-arctation of the aorta which may lead to hypertension. Other cardiac malformations include biscuspid aortic valve and mitral valve prolapse. 30-60% have genito-urinary abnormalities such as horseshoe kidneys. There is an increased risk of thyroid disease, diabetes, osteoporosis and deafness.

Hypertension is usually secondary to co-arctation of the aorta
