DISCLAIMER
In general 70% of sSMC carriers are clinically normal. The figures listed above

are based on the bias, that mainly clinically aberrant cases are studied and reported in literature!

AMA and increased fetal nuchal translucency thickness in ultrasound in week 17 of pregnancy; termination of pregnancy; autopsy showed a male fetus with small, flat nose and broad nose bridge. Eyes, ears, mouth and palate were normal. The neck was broad. All body measurements were within normal limits for gestational age (weight:544 g; length: 20 cm; head circumference: 21 cm; femur length: 4.0 cm; foot length: 4.2 cm).
