Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 1P and 12B. PP3BP6_Very_StrongBS2

The NM_014008.5(CCDC22):c.1636G>A(p.Asp546Asn) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.00518 in 1,203,580 control chromosomes in the GnomAD database, including 16 homozygotes. There are 1,906 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D546H) has been classified as Uncertain significance.

Genes affected

CCDC22 (HGNC:28909): (coiled-coil domain containing 22) This gene encodes a protein containing a coiled-coil domain. The encoded protein functions in the regulation of NF-kB (nuclear factor kappa-light-chain-enhancer of activated B cells) by interacting with COMMD (copper metabolism Murr1 domain-containing) proteins. The mouse orthologous protein has been shown to bind copines, which are calcium-dependent, membrane-binding proteins that may function in calcium signaling. This human gene has been identified as a novel candidate gene for syndromic X-linked intellectual disability. [provided by RefSeq, Aug 2013]
