Sanjad-Sakati syndrome/Kenny- Caffey syndrome type 1: a study of 21 cases in Kuwait

We studied 21 patients with Sanjad-Sakati syndrome (SSS) from 16 families. Parental consanguinity was recorded in 2 families (12.5%). All patients had severe intrauterine growth retarda- tion, short stature, small hands and feet, blue sclera, deep-set eyes, microcephaly, persistent hypo- calcaemia and hypoparathyroidism. Medullary stenosis was detected in 2 patients. Cytogenetic and fluorescent in situ hybridization studies were normal. All affected persons had homozygous deletion of 12 bp (155-166del) in exon 3 of the TBCE gene. All of the parents were heterozygous carriers of this mutation. The high frequency of SSS and low frequency of consanguineous marriages in this study may reflect a high rate of heterozygous carriers. تيوكلا في ةلاح 21 ةسارد :يط ق س - دجنس ةمزلاتم نم لولأا طمنلا
