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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2021The c.103C>G (p.R35G) alteration is located in exon 1 (coding exon 1) of the CYBRD1 gene. This alteration results from a C to G substitution at nucleotide position 103, causing the arginine (R) at amino acid position 35 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
