Genes affected

AMBRA1 (HGNC:25990): (autophagy and beclin 1 regulator 1) Enables GTPase binding activity and ubiquitin protein ligase binding activity. Involved in macroautophagy; positive regulation of phosphatidylinositol 3-kinase activity; and response to mitochondrial depolarisation. Located in cytosol. Colocalizes with mitochondrion. Biomarker of multiple system atrophy. [provided by Alliance of Genome Resources, Apr 2022]

The c.2905G>A (p.V969I) alteration is located in exon 17 (coding exon 16) of the AMBRA1 gene. This alteration results from a G to A substitution at nucleotide position 2905, causing the valine (V) at amino acid position 969 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
