Turner

When someone says Turner Syndrome, what do you think about?

Aortic Coarctation (preductal type):

hypotension and lower extremity cyanosis which causes rib notching = erosion of lower border of the ribs from enlargement of the intercostals which provide collateral blood flow

Primary Amenorrhea 

Ovary streaks = lack of sex hormones 

Most common sex chromosome abnormality in females

Complete or partial monosomy of the X chromosome (45XO)

50%+ = complete loss of the X chromosome = no Barr body the remaining = mosaicism (46XY) which makes the at risk for gonadoblastoma

Patient described as Short, wide spaced nipples, delayed puberty, weak pulses of lower extremities, can have hypothyroidism and diabetes. Xray - rib notching.

That is what I think of when I here Turner Syndrome. 

Turner = trapped in Tanner stage 1
