An isolated form of congenital aplasia of the uterus and two thirds of the vagina occurring in otherwise phenotypically normal females. Most often diagnosed in adolescence as the first symptom is most commonly a primary amenorrhoea in young women presenting with otherwise normal development of secondary sexual characteristics and normal external genitalia. Patients lack the uterus and the upper two thirds of the vagina. The exact aetiology of MRKH syndrome remains largely unknown, the disease was thought to be purely sporadic but in familial cases it seems to be inherited as an autosomal dominant trait with incomplete penetrance and variable expressivity. |

A rare genetic lethal multiple congenital anomalies/dysmorphic syndrome characterized by severe hydranencephaly and renal dysplasia or agenesis. Pregnancy is complicated by oligo- or anhydramnios, leading to features of Potter sequence (including typical facies and microretrognathia, limb contractures, talipes equinovarus, and pulmonary hypoplasia) in the fetus. Affected fetuses either die in utero or shortly after birth. Histology of the brain shows widespread presence of multinucleated neurons and glial cells. |

NDE1-related microhydranencephaly is a rare, hereditary syndrome with a central nervous system malformation as major feature characterized by extreme microcephaly and growth restriction, severe motor delay and mental retardation, and typical radiological findings of gross dilation of the ventricles resulting from the absence (or severe delay in the development) of cerebral hemispheres, hypoplasia of the corpus callosum, cerebellum, and brainstem. Associated features are thin bones and scalp rugae. |
