Genes affected

AJUBA (HGNC:20250): (ajuba LIM protein) Enables alpha-catenin binding activity and transcription corepressor activity. Involved in several processes, including negative regulation of hippo signaling; positive regulation of gene silencing by miRNA; and regulation of cellular response to hypoxia. Acts upstream of or within gene silencing by miRNA and positive regulation of protein-containing complex assembly. Located in several cellular components, including Golgi apparatus; P-body; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000259132 (HGNC:):

AJUBA-DT (HGNC:55449): (AJUBA divergent transcript)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19756478).
