Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.763G>A (p.E255K) alteration is located in exon 6 (coding exon 6) of the SLC25A23 gene. This alteration results from a G to A substitution at nucleotide position 763, causing the glutamic acid (E) at amino acid position 255 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
