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 retardation, short stature, small hands and feet, blue sclera, deep-set eyes, microcephaly, persistent hypocalcaemia 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. ‫الكويت‬ ‫يف‬ ‫حالة‬

We describe 3 sibs, two females and a male, with hypogonadism, defective Müllerian development in the sisters, and partial alopecia consisting of cranial hair only in the center of the scalp. One sister had absent gonads, the other had streak ovaries; both had markedly hypoplastic internal genitalia. Their brother had hormonal and histologic findings consistent with germinal cell aplasia. In view of the fact that the parents were consanguineous, autosomal recessive inheritance of the syndrome is likely.

Infertility is one of the major public health problems, affecting 15% of couples who attempt pregnancy; in 50% of these, the male partner is responsible. Chromosomal abnormalities and Y microdeletions in the azoospermia factor (AZF) region are known to be associated with spermatogenetic failure. In the present study, 289 patients with primary male infertility because of spermatogenetic failure were studied in order to highlight the molecular background of male infertility in Kuwait, and to avoid the possibility of transmission of any microdeletions/chromosomal aberrations to offspring via intracytoplasmic sperm injection (ICSI). Of the 289 infertile men, 23 patients (8%) had chromosomal aberration in the form of Klinefelter syndrome/variant (16/23; 69.6%), XYY syndrome (3/23; 13%), XX male syndrome (2/23; 8.7%), 45,X/46X, i(Yp)(1/23; 4.4%) and 45,XY, t(9;22) (1/23;4.4%). Y-chromosome microdeletion in the AZFb and AZFc regions were detected in 7/266 cases (2.6%). Testicular biopsy was carried out in 31 azoospermic patients, of whom five men had Sertoli-cell only syndrome, while 26 patients had spermatogenic arrest. In conclusion, this study showed that the frequency of both chromosomal anomalies and Y microdeletions were found in 10.4% of the infertile men. The potential risk of transmitting these genetic disorders to offspring provides a rationale for screening infertile men prior to ICSI.

A stratified representative sample size of 5,007 Kuwaiti females aged 15 years and above was drawn during 1983 and structurally interviewed to study the influence of consanguineous marriages (up to the second cousin) on reproductive wastage. Losses comprised prenatal deaths (abortions and stillbirths) and neonatal deaths (up to the first month of life). The rate of consanguineous mating in the sample was 54.3% with 95% confidence limits estimated rate 52.9% to 55.7% when projected over the whole Kuwaiti population. First cousin marriages accounted for 30.2% of the sample followed by 22.1 YO less than first cousin (first cousin once removed and second cousins) and 2% only double first cousin. The study showed higher prenatal and neonatal losses among consanguineous (l4.2%, 2.97%) than nonconsanguineous (13.97%, 2.54%) although not statistically significant. No consistent increase in reproductive wastage was evident as the inbreeding coefficient, F, advances mainly because of decline in the wastage rate among the double first cousin marriages which represents only 2% of our sample.

Trisomy 18 birth prevalence rate is high in Kuwait with advanced maternal age as a significant risk factor.
