Genes affected

CYB561A3 (HGNC:23014): (cytochrome b561 family member A3) Predicted to enable transmembrane ascorbate ferrireductase activity. Predicted to be involved in cellular iron ion homeostasis. Located in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

CYB561A3 links:

TKFC (HGNC:24552): (triokinase and FMN cyclase) This gene is a member of the family of dihydroxyacetone kinases, which have a protein structure distinct from other kinases. The product of this gene phosphorylates dihydroxyacetone, and also catalyzes the formation of riboflavin 4',5'-phosphate (aka cyclin FMN) from FAD. Several alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2017]

The c.733C>G (p.P245A) alteration is located in exon 7 (coding exon 5) of the CYB561A3 gene. This alteration results from a C to G substitution at nucleotide position 733, causing the proline (P) at amino acid position 245 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
