Record overview

MITO ID	MT000023
Gene ID	212
Species	Homo sapiens (Human)
Gene Name	5'-aminolevulinate synthase 2
Gene Symbol	ALAS2
Synonyms	ASB; ANH1; XLSA; ALASE; XLDPP; XLEPP; ALAS-E;
Alternate names	5-aminolevulinate synthase, erythroid-specific, mitochondrial; delta-ALA synthase 2; delta-ALA synthetase; 5-aminolevulinic acid synthase 2; delta-aminolevulinate synthase 2; aminolevulinate, delta-, synthase 2;
Chromosome	X
Map Location	Xp11.21
EC Number	2.3.1.37
Summary	The product of this gene specifies an erythroid-specific mitochondrially located enzyme. The encoded protein catalyzes the first step in the heme biosynthetic pathway. Defects in this gene cause X-linked pyridoxine-responsive sideroblastic anemia. Alternatively spliced transcript variants encoding different isoforms have been identified.
