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]

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Lys803Argfs*5) in the ANKRD11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ANKRD11 are known to be pathogenic (PMID: 21782149, 25125236, 25413698, 25652421). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with KBG syndrome (PMID: 27667800). ClinVar contains an entry for this variant (Variation ID: 266033). For these reasons, this variant has been classified as Pathogenic. -

The c.2408_2412delAAAAA (p.K803Rfs*5) alteration, located in exon 9 (coding exon 7) of the ANKRD11 gene, consists of a deletion of 5 nucleotides from position 2408 to 2412, causing a translational frameshift with a predicted alternate stop codon after 5 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This alteration has been reported as de novo in multiple unrelated individuals with clinical features of KBG syndrome (Parenti, 2021; Gnazzo, 2020). Additional heterozygous individuals with ANKRD11 variants have been reported in the literature (Low, 2016; Bestetti, 2022). Based on the available evidence, this alteration is classified as pathogenic. -

The ANKRD11 c.2408_2412del5 variant is predicted to result in a frameshift and premature protein termination (p.Lys803Argfs*5). This variant has been reported in multiple unrelated individuals with KBG syndrome (Low et al. 2016. PubMed ID: 27667800; Bianchi et al. 2017. PubMed ID: 29224748; Wright et al. 2021. PubMed ID: 33149276; Parenti et al. 2021. PubMed ID: 33955014; Marangoni et al. 2021. PubMed ID: 34906519; Digilio et al. 2021. PubMed ID: 34971082; Tal-Ben Ishay et al. 2021. PubMed ID: 35052376; Loberti et al. 2022. PubMed ID: 35861666). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Frameshift variants in ANKRD11 are expected to be pathogenic. This variant is interpreted as pathogenic. -
