Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.38A>G (p.E13G) alteration is located in exon 2 (coding exon 1) of the SFXN1 gene. This alteration results from a A to G substitution at nucleotide position 38, causing the glutamic acid (E) at amino acid position 13 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
