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.

A study in humans demonstrated that a rapid, sensitive, and specific test for blood identification was developed by integrating Reverse Transcriptase-Recombinase Polymerase Amplification with CRISPR-Cas12a and lateral flow assay, using the blood-specific RNA marker ALAS2 as a model [Su et al. DOI:10.1016/j.fsigen.2024.103098]. The assay detected the ALAS2 in all peripheral blood and some menstrual blood samples but not in semen, saliva, or vaginal fluid, with a detection limit of 0.195 ng extracted RNA or 0.0218 μL liquid peripheral blood, and it successfully identified blood in mixtures with saliva and on reconstituted bloodstains, showing potential for crime scene use.
