not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 21, 2024The c.241G>A (p.D81N) alteration is located in exon 3 (coding exon 2) of the SFXN2 gene. This alteration results from a G to A substitution at nucleotide position 241, causing the aspartic acid (D) at amino acid position 81 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
