Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2024The c.173T>G (p.I58S) alteration is located in exon 4 (coding exon 2) of the CYB561A3 gene. This alteration results from a T to G substitution at nucleotide position 173, causing the isoleucine (I) at amino acid position 58 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
