Research Abstract

Many cases of maple syrup urine disease (MSUD) have been identified in the Philippines. To enhance early diagnosis of MSUD, applicability of neonatal screening of MSUD was examined in Metro Manila.
Within this year 6 new MSUD patients were identified by finding abnormal smell in the very sick neonates. These patients were treated well and are developing well under the nutritional treatment.
In our previous study one unique mutation of the E2 gene is identified and found as a founder mutation among Philippino. Therefore, this mutation was analyzed in these 6 new cases. PCR application of the region spreading from exon 9 to 10 showed no shortened product. This indicates that these 6 patients had no deletion mutations. Then every exon of the E2 gene is now under sequence examination.
Our results indicate that one mutation is not common among Philippines but several types of mutation be presert.
