Genes affected
FRRS1 (HGNC:27622): (ferric chelate reductase 1) Members of the cytochrome b561 (CYB561; MIM 600019) family, including FRRS1, reduce ferric to ferrous iron before its transport from the endosome to the cytoplasm (Vargas et al., 2003 [PubMed 14499595]).[supplied by OMIM, Mar 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.1700T>C (p.V567A) alteration is located in exon 17 (coding exon 15) of the FRRS1 gene. This alteration results from a T to C substitution at nucleotide position 1700, causing the valine (V) at amino acid position 567 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
