Genes affected

RAC3 (HGNC:9803): (Rac family small GTPase 3) The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

The c.260C>T (p.P87L) alteration is located in exon 4 (coding exon 4) of the RAC3 gene. This alteration results from a C to T substitution at nucleotide position 260, causing the proline (P) at amino acid position 87 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
