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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.3170C>T (p.A1057V) alteration is located in exon 19 (coding exon 18) of the AMBRA1 gene. This alteration results from a C to T substitution at nucleotide position 3170, causing the alanine (A) at amino acid position 1057 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
