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]

The c.178T>C (p.F60L) alteration is located in exon 1 (coding exon 1) of the CYBRD1 gene. This alteration results from a T to C substitution at nucleotide position 178, causing the phenylalanine (F) at amino acid position 60 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
