Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2024The c.190G>A (p.V64M) 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 190, causing the valine (V) at amino acid position 64 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
