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]

Ambry Genetics

Nov 24, 2024

The c.605A>C (p.N202T) alteration is located in exon 7 (coding exon 5) of the CYB561A3 gene. This alteration results from a A to C substitution at nucleotide position 605, causing the asparagine (N) at amino acid position 202 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
