Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2023The c.308C>T (p.T103M) alteration is located in exon 3 (coding exon 2) of the SFXN2 gene. This alteration results from a C to T substitution at nucleotide position 308, causing the threonine (T) at amino acid position 103 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
