Genes affected

MCU (HGNC:23526): (mitochondrial calcium uniporter) Enables calcium channel activity; identical protein binding activity; and uniporter activity. Involved in several processes, including positive regulation of mitochondrial calcium ion concentration; positive regulation of mitochondrial fission; and positive regulation of neutrophil chemotaxis. Acts upstream of or within calcium import into the mitochondrion. Located in mitochondrial inner membrane. Is integral component of mitochondrial inner membrane. Part of uniplex complex.

The c.107G>C (p.G36A) alteration is located in exon 1 (coding exon 1) of the MCU gene. This alteration results from a G to C substitution at nucleotide position 107, causing the glycine (G) at amino acid position 36 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
