Genes affected

MIEF1 (HGNC:25979): (mitochondrial elongation factor 1) Enables ADP binding activity; GDP binding activity; and identical protein binding activity. Involved in several processes, including positive regulation of mitochondrial fission; positive regulation of mitochondrial translation; and positive regulation of protein targeting to membrane. Located in mitochondrial matrix and mitochondrial outer membrane. Colocalizes with mitochondrial large ribosomal subunit. [provided by Alliance of Genome Resources, Apr 2022]

Feb 14, 2023

The c.673A>G (p.M225V) alteration is located in exon 6 (coding exon 4) of the MIEF1 gene. This alteration results from a A to G substitution at nucleotide position 673, causing the methionine (M) at amino acid position 225 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
