Variable expressivity of congenital longitudinal radial deficiency and spinal dysraphism in monozygotic twins.
نویسندگان
چکیده
We report monozygotic twins with longitudinal radial hypoplasia and low (L5) spina bifida occulta, but with differing severity. There is only one previous report of similar twins. We report these identical twins with the expression of longitudinal radial hypoplasia with mirror image pattern on contralateral sides, and the association of low spina bifida occulta.

Since identical twins occur as a result of the division of one egg, they have the same genetic structure. Therefore, their phenotypes and sex are also always the same. However, due to the effect of environmental factors, some of the characteristics of twins living in different regions appear to develop differently. In our case of 17-year-old maternal twins, we emphasized that nasal pathologies ...
متن کاملAntenatal Diagnosis of Bilateral Renal Agenesis in One of a Twin Pair
Bilateral renal agenesis (BRA) was diagnosed antenatally in one of like-sexed (probably monozygotic) twins. This is the first report of such a diagnosis. The difficulties of certain sonographic diagnosis of BRA are outlined and are possibly compounded in twin pregnancy in the presence of growth retardation/oligohydramnios of one of the twins. Recent evidence suggests that BRA is inherited in an...
