Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.37C>G (p.R13G) alteration is located in exon 1 (coding exon 1) of the MRS2 gene. This alteration results from a C to G substitution at nucleotide position 37, causing the arginine (R) at amino acid position 13 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
