Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.224A>G (p.Y75C) alteration is located in exon 3 (coding exon 2) of the SFXN1 gene. This alteration results from a A to G substitution at nucleotide position 224, causing the tyrosine (Y) at amino acid position 75 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
