Genes affected

CLIP2 (HGNC:2586): (CAP-Gly domain containing linker protein 2) The protein encoded by this gene belongs to the family of cytoplasmic linker proteins, which have been proposed to mediate the interaction between specific membranous organelles and microtubules. This protein was found to associate with both microtubules and an organelle called the dendritic lamellar body. This gene is hemizygously deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternative splicing of this gene generates 2 transcript variants. [provided by RefSeq, Jul 2008]

The c.412A>C (p.I138L) alteration is located in exon 3 (coding exon 2) of the CLIP2 gene. This alteration results from a A to C substitution at nucleotide position 412, causing the isoleucine (I) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
