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]

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	May 24, 2024	Variant summary: ANKRD11 c.3418G>A (p.Ala1140Thr) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251250 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.3418G>A in individuals affected with KBG Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 434199). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces alanine with threonine at codon 1140 of the ANKRD11 protein (p.Ala1140Thr). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and threonine. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ANKRD11 protein function. ClinVar contains an entry for this variant (Variation ID: 434199). This variant has not been reported in the literature in individuals affected with ANKRD11-related conditions. This variant is present in population databases (rs369869329, ExAC no frequency). -

The c.3418G>A (p.A1140T) alteration is located in exon 9 (coding exon 7) of the ANKRD11 gene. This alteration results from a G to A substitution at nucleotide position 3418, causing the alanine (A) at amino acid position 1140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
