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 GeneticsJun 21, 2022The c.343A>G (p.N115D) 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 343, causing the asparagine (N) at amino acid position 115 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
