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]

Ambry Genetics

May 27, 2022

The c.862C>T (p.R288C) alteration is located in exon 6 (coding exon 4) of the MIEF1 gene. This alteration results from a C to T substitution at nucleotide position 862, causing the arginine (R) at amino acid position 288 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
