Genes affected

HEPH (HGNC:4866): (hephaestin) This gene encodes a member of the multicopper oxidase protein family. The encoded protein is involved in the transport of dietary iron from epithelial cells of the intestinal lumen into the circulatory system, and may be involved in copper transport and homeostasis. In mouse, defects in this gene can lead to severe microcytic anemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Sep 22, 2021

The c.963G>T (p.R321S) alteration is located in exon 5 (coding exon 5) of the HEPH gene. This alteration results from a G to T substitution at nucleotide position 963, causing the arginine (R) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
