Genes affected

PHB2 (HGNC:30306): (prohibitin 2) Enables several functions, including protein C-terminus binding activity; protein N-terminus binding activity; and protein dimerization activity. Involved in several processes, including defense response to virus; positive regulation of cell cycle phase transition; and regulation of transcription, DNA-templated. Located in several cellular components, including cell surface; mitochondrial membrane; and nuclear matrix. Part of mitochondrial prohibitin complex.

The c.114A>T (p.E38D) alteration is located in exon 1 (coding exon 1) of the PHB2 gene. This alteration results from a A to T substitution at nucleotide position 114, causing the glutamic acid (E) at amino acid position 38 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
