Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2024The c.592A>G (p.M198V) alteration is located in exon 8 (coding exon 8) of the MIOX gene. This alteration results from a A to G substitution at nucleotide position 592, causing the methionine (M) at amino acid position 198 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
