Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.101G>A (p.R34H) alteration is located in exon 2 (coding exon 1) of the SFXN2 gene. This alteration results from a G to A substitution at nucleotide position 101, causing the arginine (R) at amino acid position 34 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
