Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_004067.4(CHN2):​c.611A>C​(p.His204Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. 12/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H204R) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: CHN2 NM_004067.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 6.98

Genes affected

CHN2 (HGNC:1944): (chimerin 2) This gene encodes a guanosine triphosphate (GTP)-metabolizing protein that contains a phorbol-ester/diacylglycerol (DAG)-type zinc finger, a Rho-GAP domain, and an SH2 domain. The encoded protein translocates from the cytosol to the Golgi apparatus membrane upon binding by diacylglycerol (DAG). Activity of this protein is important in cell proliferation and migration, and expression changes in this gene have been detected in cancers. A mutation in this gene has also been associated with schizophrenia in men. Alternative transcript splicing and the use of alternative promoters results in multiple transcript variants.
