Thread: isochromosome ending up in TURNER.plz help

it is written in kaplan bio that "karyotype of an isochromosome for the long arm of X wud b 46X,i[Xq]. this karyo results in Turner syndrome,indicating that most of the critical genes responsible for Turner phenotype r on Xp". my question is that this fellow didnt get any p then how did she bcome a Turner?

It is the absence of the second chromosone OR the abnormality of the
second chromosone that causes Turner's syndrome where the ovaries
do not develop.

Signs are
Short height such as below 5ft
webbed neck
sheild chest (nipples are spread far apart and not developed)
hypergonadotropic hypoestrogenic amenorhea

Concepts
aneuploidy - change in number of chromosones. additional, missing
monosomy - missing chromosone, in humans only 45,X karyotype
karyotype - ordering of chromosones by length and position of centromere
or the notation
isochromosone - a chromosone with identical arms that are mirror images
of each other. (edit this later)
p - petite arm of chromosone
q - long arm is of chromosone is the next letter in alphabet
