BACKGROUND Previous data have shown an association between DNA sequence variants in the IRF6 gene and an increased risk of non-syndromic cleft lip with or without cleft palate (CL/P) in some populations. OBJECTIVE To investigate Thai CL/P patients and relative for a 820G-->A polymorphism. SUBJECTS 192 CL/P Thai patients, 177 of their mothers, 73 of(More)
Non-syndromic cleft lip with or without cleft palate (CL/P) is one of the most common congenital anomalies world wide. It has a prevalence of approximately 1/1000 among white populations and 1/600 among Thai newborns. Environmental and genetic factors have been implicated in CL/P and several different loci and genes have been associated with them. Maternal(More)
Guanidinated proteins when fed to non-ruminants provide values for both endogenous amino acid losses and amino acid digestibilities, provided that the homoarginine residues in the treated protein are randomly distributed. Earlier studies have established that guanidination has only minor effects on the structure of the protein and, in particular, on its(More)
Mutations in the p63 gene (TP63) underlie several monogenic malformation syndromes manifesting cleft lip with or without cleft palate (CL/P). We investigated whether p63 mutations also result in non-syndromic CL/P. Specifically, we performed mutation analysis of the 16 exons of the p63 gene for 100 Thai patients with non-syndromic CL/P. In total, 21 variant(More)
Mutations in the TBX22 gene underlie an X-linked malformation syndrome with cleft palate (CP) and ankyloglossia. Its mutations also result in non-syndromic CP in some populations. To investigate whether mutations in TBX22 play a part in the formation of non-syndromic CP in the Thai population, we performed mutation analysis covering all the coding regions(More)
Studies of human chromosomal aberrations and knockout (KO) mice have suggested SATB2 as a candidate gene for a human malformation syndrome of craniofacial patterning and brain development. Of 59 unrelated patients with craniofacial dysmorphism, with or without mental retardation, one 36-year-old man had a nonsynonymous mutation in SATB2. The affected(More)
Previous studies observed that MSX1 mutations could contribute to nonsyndromic cleft lip with or without cleft palate (CL/P) in some populations. Of the proposed pathogenic mutations, the P147Q variant was predominant in Vietnamese and present in Filipino populations. We investigated whether MSX1 mutations also contribute to nonsyndromic CL/P in the Thai(More)
1. Ileal endogenous amino acid losses were determined in broiler chickens and in cannulated cross-bred layer strain cockerels using either a nitrogen-free diet, regression analysis or a 48 h fast. 2. Endogenous amino acid flows to the ileum in fasted cockerels were significantly lower than those obtained both by feeding the nitrogen-free diet, and from(More)
BACKGROUND This study aims to assess the situation of communicable diseases under national surveillance in the Cyclone Nargis-affected areas in Myanmar (Burma) before and after the incident. METHODS Monthly data during 2007, 2008 and 2009 from the routine reporting system for disease surveillance of the Myanmar Ministry of Health (MMOH) were reviewed and(More)
Van der Woude syndrome (VWS) is a dominantly inherited disorder characterized by cleft lip with or without cleft palate and lip pits. It remains the most common syndromic form of oral clefts. Mutations in the interferon regulatory factor 6 (IRF6) gene have been identified in patients with VWS. We reported three unrelated families with lower lip anomalies.(More)
