Genes affected

BORA (HGNC:24724): (BORA aurora kinase A activator) BORA is an activator of the protein kinase Aurora A (AURKA; MIM 603072), which is required for centrosome maturation, spindle assembly, and asymmetric protein localization during mitosis (Hutterer et al., 2006 [PubMed 16890155]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16071731).

The c.245A>T (p.Y82F) alteration is located in exon 3 (coding exon 2) of the BORA gene. This alteration results from a A to T substitution at nucleotide position 245, causing the tyrosine (Y) at amino acid position 82 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
