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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.3530C>A (p.T1177N) alteration is located in exon 19 (coding exon 18) of the AMBRA1 gene. This alteration results from a C to A substitution at nucleotide position 3530, causing the threonine (T) at amino acid position 1177 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
