Genes affected

CSMD2 (HGNC:19290): (CUB and Sushi multiple domains 2) The protein encoded by this gene is thought to be involved in the control of complement cascade of the immune system. Defects in this gene have been associated with schizophrenia. This gene may act as a tumor suppressor for colorectal cancer. [provided by RefSeq, Jan 2020]

The c.9808G>T (p.G3270W) alteration is located in exon 65 (coding exon 65) of the CSMD2 gene. This alteration results from a G to T substitution at nucleotide position 9808, causing the glycine (G) at amino acid position 3270 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
