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=0.13568372).

The c.1205C>G (p.T402S) alteration is located in exon 10 (coding exon 9) of the BORA gene. This alteration results from a C to G substitution at nucleotide position 1205, causing the threonine (T) at amino acid position 402 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
