Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.841G>A (p.G281S) alteration is located in exon 4 (coding exon 1) of the MIOS gene. This alteration results from a G to A substitution at nucleotide position 841, causing the glycine (G) at amino acid position 281 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
