Genes affected

PAK1 (HGNC:8590): (p21 (RAC1) activated kinase 1) This gene encodes a family member of serine/threonine p21-activating kinases, known as PAK proteins. These proteins are critical effectors that link RhoGTPases to cytoskeleton reorganization and nuclear signaling, and they serve as targets for the small GTP binding proteins Cdc42 and Rac. This specific family member regulates cell motility and morphology. Mutations in this gene have been associated with macrocephaly, seizures, and speech delay. Overexpression of this gene is also reported in many cancer types, and particularly in breast cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2020]

The c.1630C>T (p.L544F) alteration is located in exon 16 (coding exon 15) of the PAK1 gene. This alteration results from a C to T substitution at nucleotide position 1630, causing the leucine (L) at amino acid position 544 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
