Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.106G>A (p.V36I) alteration is located in exon 1 (coding exon 1) of the MRS2 gene. This alteration results from a G to A substitution at nucleotide position 106, causing the valine (V) at amino acid position 36 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
