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]

Sep 17, 2021

The c.157C>T (p.L53F) alteration is located in exon 2 (coding exon 2) of the CCDC22 gene. This alteration results from a C to T substitution at nucleotide position 157, causing the leucine (L) at amino acid position 53 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
