Genes affected

LYRM4 (HGNC:21365): (LYR motif containing 4) The protein encoded by this gene is found in both mitochondria and the nucleus, where it binds cysteine desulfurase and helps free inorganic sulfur for Fe/S clusters. Disruption of this gene negatively impacts mitochondrial and cytosolic iron homeostasis. [provided by RefSeq, Sep 2016]

LYRM4-AS1 (HGNC:):
