Specific PATIENTINFORMATION for sSMC(16) - part 1
Specific PATIENTINFORMATION for sSMC(16) - part 2

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!

sSMC detected due to advanced maternal age; Slowing of growth in the last weeks of pregnancy and labor was induced at 37.5 weeks. Weight was 2.55 kg; length 46.5 cm; scars at two sites on her left thigh from the fetal skin biopsy; deep sacral dimple, ultrasound of underlying structures was normal. Neonatal course also was normal. At 7 months of age she sits with assistance and is close to sitting alone. The remainder of developmental assessment is also normal for age. Normal at age of 4.5 y.
