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 GeneticsMar 15, 2024The c.3446C>T (p.P1149L) 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 3446, causing the proline (P) at amino acid position 1149 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
