Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.179A>C (p.N60T) alteration is located in exon 3 (coding exon 3) of the CYB5R1 gene. This alteration results from a A to C substitution at nucleotide position 179, causing the asparagine (N) at amino acid position 60 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
