Genes affected

SAMM50 (HGNC:24276): (SAMM50 sorting and assembly machinery component) This gene encodes a component of the Sorting and Assembly Machinery (SAM) of the mitochondrial outer membrane. The Sam complex functions in the assembly of beta-barrel proteins into the outer mitochondrial membrane.[provided by RefSeq, Jun 2011]

The c.464G>A (p.R155H) alteration is located in exon 6 (coding exon 6) of the SAMM50 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the arginine (R) at amino acid position 155 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
