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 GeneticsSep 14, 2022The c.286C>T (p.L96F) alteration is located in exon 2 (coding exon 2) of the CYBRD1 gene. This alteration results from a C to T substitution at nucleotide position 286, causing the leucine (L) at amino acid position 96 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
