Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM4BS2

The NM_013275.6(ANKRD11):c.6112_6132delAAGGACGGAGTGGACGCCGTC(p.Lys2038_Val2044del) variant causes a conservative inframe deletion change. The variant allele was found at a frequency of 0.0000115 in 1,563,018 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Uncertain significance (★★).

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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 547991). This variant has not been reported in the literature in individuals affected with ANKRD11-related conditions. This variant is present in population databases (rs748553966, gnomAD 0.006%). This variant, c.6112_6132del, results in the deletion of 7 amino acid(s) of the ANKRD11 protein (p.Lys2038_Val2044del), but otherwise preserves the integrity of the reading frame. -
