Genes affected

BECN1 (HGNC:1034): (beclin 1) This gene encodes a protein that regulates autophagy, a catabolic process of degradation induced by starvation. The encoded protein is a component of the phosphatidylinositol-3-kinase (PI3K) complex which mediates vesicle-trafficking processes. This protein is thought to play a role in multiple cellular processes, including tumorigenesis, neurodegeneration and apoptosis. Alternative splicing results in multiple transcript variants.

The c.1061C>G (p.S354C) alteration is located in exon 11 (coding exon 10) of the BECN1 gene. This alteration results from a C to G substitution at nucleotide position 1061, causing the serine (S) at amino acid position 354 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
