Gonadal dysgenesis, XY female type, is associated with point mutations or deletions of the SRY gene ,but also in some cases with changes in the X chromosome

46,X,i(Xp) 'i(Xp)' is for isochromasis on short arm of X ,causing Xp duplication

Small deletions in the short arm of the Y chromosome can result in 46,XY females
