Genes affected

CC2D1A (HGNC:30237): (coiled-coil and C2 domain containing 1A) This gene encodes a transcriptional repressor that binds to a conserved 14-bp 5'-repressor element and regulates expression of the 5-hydroxytryptamine (serotonin) receptor 1A gene in neuronal cells. The DNA binding and transcriptional repressor activities of the protein are inhibited by calcium. A mutation in this gene results in a nonsyndromic form of cognitive disability (MRT3).

The p.R911G variant (also known as c.2731C>G), located in coding exon 27 of the CC2D1A gene, results from a C to G substitution at nucleotide position 2731. The arginine at codon 911 is replaced by glycine, an amino acid with dissimilar properties. This variant was previously reported in the SNPDatabase as rs200848845. Based on data from the NHLBI Exome Sequencing Project (ESP), the G allele has an overall frequency of approximately 0.01% (1/12186) total alleles studied, having been observed in 0.03% (1/3922) African American alleles. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. -
