Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.815A>C (p.D272A) alteration is located in exon 9 (coding exon 9) of the CYB5R1 gene. This alteration results from a A to C substitution at nucleotide position 815, causing the aspartic acid (D) at amino acid position 272 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
