Genes affected

ATG4C (HGNC:16040): (autophagy related 4C cysteine peptidase) Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels of autophagy have been described in some malignant tumors, and a role for autophagy in controlling the unregulated cell growth linked to cancer has been proposed. This gene encodes a member of the autophagin protein family. The encoded protein is also designated as a member of the C-54 family of cysteine proteases. Alternate transcriptional splice variants, encoding the same protein, have been characterized. [provided by RefSeq, Jul 2008]

The c.1153G>A (p.G385R) alteration is located in exon 10 (coding exon 9) of the ATG4C gene. This alteration results from a G to A substitution at nucleotide position 1153, causing the glycine (G) at amino acid position 385 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
