Genes affected

ATG3 (HGNC:20962): (autophagy related 3) This gene encodes a ubiquitin-like-conjugating enzyme and is a component of ubiquitination-like systems involved in autophagy, the process of degradation, turnover and recycling of cytoplasmic constituents in eukaryotic cells. This protein is known to play a role in regulation of autophagy during cell death. A pseudogene of this gene is located on chromosome 20. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]

The c.437A>T (p.E146V) alteration is located in exon 7 (coding exon 7) of the ATG3 gene. This alteration results from a A to T substitution at nucleotide position 437, causing the glutamic acid (E) at amino acid position 146 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
