Genes affected

CYBRD1 (HGNC:20797): (cytochrome b reductase 1) This gene is a member of the cytochrome b(561) family that encodes an iron-regulated protein. It highly expressed in the duodenal brush border membrane. It has ferric reductase activity and is believed to play a physiological role in dietary iron absorption. [provided by RefSeq, Jul 2008]

Dec 21, 2023

The c.292A>G (p.I98V) alteration is located in exon 2 (coding exon 2) of the CYBRD1 gene. This alteration results from a A to G substitution at nucleotide position 292, causing the isoleucine (I) at amino acid position 98 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
