Genes affected

MAEA (HGNC:13731): (macrophage erythroblast attacher, E3 ubiquitin ligase) This gene encodes a protein that mediates the attachment of erythroblasts to macrophages. This attachment promotes terminal maturation and enucleation of erythroblasts, presumably by suppressing apoptosis. The encoded protein is an integral membrane protein with the N-terminus on the extracellular side and the C-terminus on the cytoplasmic side of the cell. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.1114C>A (p.Q372K) alteration is located in exon 9 (coding exon 9) of the MAEA gene. This alteration results from a C to A substitution at nucleotide position 1114, causing the glutamine (Q) at amino acid position 372 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
