About ALAS2

Cytogenetic location: Xp11.21 Genomic coordinates (GRCh38): X:55,009,055-55,030,977 (from NCBI)

This gene has 9 transcripts (splice variants), 191 orthologues, 5 paralogues and is associated with 4 phenotypes. Restricted expression toward bone marrow (RPKM 181.6).

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.
