The expanding spectrum of disorders with elevated plasma chitotriosidase activity: an update.

abstract：:This study reports three novel mutations of the methionine adenosyltransferase (MAT) lA gene and confirms that hyperhomocysteinaemia may be a characteristic finding in MAT I/III deficiency. Thus, MAT I/III deficiency is important in the differential diagnoses of hyperhomocysteinaemia, which may lead to clinical compli...
