Waardenburg`s syndrome is a rare hereditary disease, which is characterized by dystopia canthorum, hypochromic heterochromic iridum, sensorineural deafness,high and broad nasal bridge, white forelock and premature graying. We present a case of 27 year old woman with Waardenburg`s syndrome. She has characteristic features such as dystopia canthorum, broad and high nasal bridge, confluent eyebrow(synophrys), hypochromic heterochromic iridum, depigmented fundus and premature graying.

Background: \u03b2-thalassemia is a hereditary disease caused by disorder in \u03b2-globin chain synthesis process. In this research, multiplex-PCR was used in combination with blood chemistry assays and clinical symptoms to detect \u03b2-globin mutations. Objectives: (1) to identify the \u03b2-thalassemia mutation spectrum in the North of Vietnam; (2) to determine the relation between biochemistry values and types of mutations. Subject and methods: Blood samples collected from 60 pediatric patients were used in screening assays (hemoglobin counting, red blood cell counting, hematocrit\ufffd? and multiplex-PCR to detect 6 point mutations with high prevalence in the region. Results: \r\n', u'(1) Of 60 blood samples collected from pediatric patients, 30 (50%) had mutation in codon 17 (A\u2192T), 6 (10%) had a frameshift mutation in codons 41/42 and 4 (6%) had both types of these mutations; (2) The average onset time in patients with FS 41/42 mutation was earlier than that of patients with codon 17 (A\u2192T) mutation, whereas transfusion interval did not differ significantly among these patients; (3) Mean corpuscular volume (MCV) was lower in patients with homozygous mutations (\u03b2o) (average 64.8) than in those with heterozygous mutations (\u03b2+) (average 72.7). Conclusions: (1) multiplex-PCR is an effective technique in identifying the mutation spectrum of \u03b2-globin gene in the North of Vietnam; (2) Biochemistry assays should be associated with molecular techniques in diagnose of \u03b2-thalassemia\r\n', u'\r\n', u'\r\n', u'

Background. X-linked adrenoleukodystrophy (X-ALD) is a progressive genetic disorder affecting the metabolism of very long chain fatty acids in the adrenal glands, spinal cord and white matter of the nervous system. It is an inherited metabolic storage disease whereby a defect in a specific enzyme results in the accumulation of very long-chain fatty acids (VLCFA) that are harmful to some cells and organs. VLCFA analysis for confirmation of X-linked adrenoleukodystrophy is one of the most requested tests among the send-out laboratory services of the Biochemical Genetics Laboratory at the Institute of Human Genetics. This paper aims to review the clinical characteristics and the results of the VLCFA analysis of the patients whose samples we received for testing.Methods. Overseas tests samples received by the Biochemical Genetics Laboratory for VLCFA from 2002-2016 were included. The details of the patients were collated in an overseas tests database and was the main source of the data for this study. The results of the VLCFA tests sent to the Kennedy Krieger Institute and The Children’s Hospital at Westmead were inputted into the said database. Descriptive statistics was utilized in order to examine the clinical and biochemical data of the patients.Results. The results showed that out of the 54 samples submitted to our laboratory, 19 (35%) of the samples received from male patients suspected to have X-ALD yielded positive results and another 10 (19%) females were found to be carriers. Visual defect followed by deteriorating mental status were the most frequent indications for VLCFA testing. Conclusion. Having a significant diagnostic yield of 54%, early diagnosis of X-linked adrenoleukodystrophy in our population is important so that proper management that could prevent the progression of the disease could be timely instituted.

We report the first two diagnosed cases of Glutaric Aciduria Type I (GA I) in the Philippines. The diagnosis was confirmed by urinary organic acid analysis by Gas Chromatography-Mass Spectrometry (GC-MS) which showed the characteristic metabolites for GA I. Review of their clinical features showed macrocephaly, developmental delay, seizures, dystonia and choreoathetotic posturing. Cranial CT scan findings were also compatible with previously reported cases. This paper emphasizes the usefulness of locally available biochemical tools in the diagnosis of inborn errors of metabolism as well as the importance of clinical recognition of these disorders.
