Genes affected

ANKRD11 (HGNC:21316): (ankyrin repeat domain containing 11) This locus encodes an ankryin repeat domain-containing protein. The encoded protein inhibits ligand-dependent activation of transcription. Mutations in this gene have been associated with KBG syndrome, which is characterized by macrodontia, distinctive craniofacial features, short stature, skeletal anomalies, global developmental delay, seizures and intellectual disability. Alternatively spliced transcript variants have been described. Related pseudogenes exist on chromosomes 2 and X. [provided by RefSeq, Jan 2012]

This variant, c.4475_4498dup, results in the insertion of 8 amino acid(s) of the ANKRD11 protein (p.Leu1492_Glu1499dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs762626265, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with ANKRD11-related conditions. ClinVar contains an entry for this variant (Variation ID: 373985). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
