Kallmann syndrome (KS) is a clinically and genetically heterogeneous disorder characterized by hypogonadotropic hypogonadism and olfactory dysfunction. Recently, mutations in SOX10, a well-known causative gene of Waardenburg syndrome (WS), have been identified in a few KS patients with additional developmental defects including hearing loss. However, the understanding of SOX10 mutation associates with KS and other clinical consequences remains fragmentary. A 30-year-old Chinese male patient presented with no pubertal sex development when he was at the age of twelve years...

Hemoglobin Bart's hydrops fetalis (homozygous α0 -thalassemia) is the most severe form of thalassemia in the Southeast Asian population. Fetuses with this disorder almost always die in utero or shortly after birth. Screening of α0 -thalassemia carrier is therefore crucial. Currently, diagnosis of α0 -thalassemia genes is done by DNA-based analysis which relies on DNA extraction. We have developed a simple screening format based on whole blood PCR assay. The method was validated on 198 specimens and the results show 100% concordance with a conventional gap-PCR on DNA specimens...
