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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.1010G>A (p.R337Q) alteration is located in exon 10 (coding exon 8) of the FRRS1 gene. This alteration results from a G to A substitution at nucleotide position 1010, causing the arginine (R) at amino acid position 337 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
