Genes affected

MUL1 (HGNC:25762): (mitochondrial E3 ubiquitin protein ligase 1) Enables several functions, including p53 binding activity; ubiquitin protein ligase binding activity; and ubiquitin-like protein transferase activity. Involved in several processes, including negative regulation of defense response; positive regulation of cellular protein metabolic process; and regulation of mitochondrion organization. Located in several cellular components, including mitochondrion; neuronal cell body; and peroxisome. Is integral component of mitochondrial outer membrane.

Feb 07, 2023

The c.1025C>T (p.A342V) alteration is located in exon 4 (coding exon 4) of the MUL1 gene. This alteration results from a C to T substitution at nucleotide position 1025, causing the alanine (A) at amino acid position 342 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
