Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.434G>C (p.R145P) alteration is located in exon 2 (coding exon 2) of the MICU3 gene. This alteration results from a G to C substitution at nucleotide position 434, causing the arginine (R) at amino acid position 145 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
