What is the adult height formula for Turner syndrome?

Mean adult height without GH is MPH - 20 cm (MPH = (father height + mother height - 13) / 2 + 6.5); with GH therapy, gain is typically 5-8 cm above predicted untreated height.

When should growth hormone be started in Turner syndrome?

GH therapy at dose 0.045-0.050 mg/kg/day should begin when height falls below -2 SD for age, typically age 4-8 years; starting earlier allows longer treatment duration and better final height.

What karyotype predicts shortest final height in Turner?

Pure 45,X has the lowest adult height (mean 142-143 cm in Europe); mosaicism 45,X/46,XX is taller; isochromosome Xq has intermediate stature; SHOX haploinsufficiency is the primary driver of short stature.

What cardiac monitoring is required in Turner syndrome?

Bicuspid aortic valve (25-50%), coarctation of the aorta (10%), and dilated ascending aorta require echocardiogram at diagnosis, then every 5 years (more frequently with established abnormalities).

What estrogen replacement protocol is used in Turner syndrome?

Start low-dose estrogen at 11-12 years (bone age 10-11 years); conjugated estrogens 0.15-0.3 mg/day or transdermal estradiol 3.1-6.25 mcg/day; increase over 2-3 years; add progesterone after 12 months of estrogen.
