Genes affected

SCAI (HGNC:26709): (suppressor of cancer cell invasion) This gene encodes a regulator of cell migration. The encoded protein appears to function in the RhoA (ras homolog gene family, member A)-Dia1 (diaphanous homolog 1) signal transduction pathway. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2010]

The c.1604G>A (p.R535H) alteration is located in exon 17 (coding exon 17) of the SCAI gene. This alteration results from a G to A substitution at nucleotide position 1604, causing the arginine (R) at amino acid position 535 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
