Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2

The ENST00000318003.11(CC2D1A):c.1996A>G(p.Asn666Asp) variant causes a missense change. The variant allele was found at a frequency of 0.0000285 in 1,614,010 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N666S) has been classified as Uncertain significance.

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 c.1996A>G (p.N666D) alteration is located in exon 18 (coding exon 18) of the CC2D1A gene. This alteration results from a A to G substitution at nucleotide position 1996, causing the asparagine (N) at amino acid position 666 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
