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]

SCAI (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.900C>G (p.D300E) alteration is located in exon 10 (coding exon 10) of the SCAI gene. This alteration results from a C to G substitution at nucleotide position 900, causing the aspartic acid (D) at amino acid position 300 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
