Williams-Beuren syndrome (WBS) occurs sporadically; however, at least four familial cases of WBS have been described previously. We describe a mother and her son with typical WBS. The diagnosis of WBS in the son was confirmed by molecular cytogenetic analysis fluorescence in situ hybridization. He had a deletion of 7q11.23 at the ELN locus. The mother was diagnosed after the identification of WBS in her affected son. She is deceased and was thus not studied by FISH. However, her combined symptoms make it very clear that she had WBS. Two traits uncommon in WBS were observed, unilateral renal hypoplasia in the mother and a hemivertebra at L5 in the son.

Williams syndrome (WS) is associated with a deletion of the elastin gene in over 90% of cases. We report maternal serum alpha fetoprotein (MSAFP) levels in 5 women whose fetuses were later diagnosed as having WS. MSAFP levels ranged from 0.5-0.8 multiples of the median (MOM). Although further confir
The elastin gene is consistently deleted in Williams syndrome and as this protein represents the major component of the elastic fibers of the dermis, we sought to investigate skin elastic fibers in Williams syndrome as a key to unraveling extracellular matrix disorganization in this condition. Both
We describe a new case of Say syndrome. This syndrome is an autosomal dominant condition characterized by cleft palate, short stature of prenatal onset, large protruding ears and microcephaly, delayed bone age, and renal anomalies. The first report was in 1975 by Say et al. in three generations of a
