Prenatal diagnosis of Werdnig-Hoffmann disease: DNA analysis of a mummified umbilical cord using closely linked microsatellite markers

Prenat Diagn. 1994 Mar;14(3):219-22. doi: 10.1002/pd.1970140314.

Abstract

We present a case of prenatal diagnosis of Werdnig-Hoffmann disease, the most severe type of spinal muscular atrophy (SMA). DNA obtained from a mummified umbilical cord of a decreased affected brother of the index case was analysed with four closely linked microsatellite markers [EF1/2a and EF13/14 (D5S125), MAP1B, and JK53CA (D5S112)], flanking the SMA gene, on chromosome 5q11.2-13.3. The fetus was diagnosed as homozygous for the deleterious SMA gene.
