First-trimester maternal serum Schwangerschafts protein 1 (SP1) in pregnancies associated with chromosomal anomalies.

abstract：:A polymorphic short tandem repeat (STR) in intron 3 (Goltsov et al., 1993) and a variable number of tandem repeats (Hind III-VNTR) flanked by two constant Hind III sites (Golstov et al., 1992) have been recently identified in the human phenylalanine hydroxylase (PAH) gene. These polymorphisms are easily detected by th...
