Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 09, 2024The c.737A>G (p.K246R) alteration is located in exon 8 (coding exon 8) of the MICU2 gene. This alteration results from a A to G substitution at nucleotide position 737, causing the lysine (K) at amino acid position 246 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
