Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.1164C>G (p.I388M) alteration is located in exon 10 (coding exon 10) of the MRS2 gene. This alteration results from a C to G substitution at nucleotide position 1164, causing the isoleucine (I) at amino acid position 388 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
