Labcorp Genetics (formerly Invitae), Labcorp RCV000802120 SCV000941936 pathogenic Genitopatellar syndrome 2019-01-03 criteria provided, single submitter clinical testing This sequence change results in a premature translational stop signal in the KAT6B gene (p.Tyr1834*). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 240 amino acids of the KAT6B protein. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in twin brothers affected with Say-Barber-Biesecker-Young-Simpson syndrome (Invitae). This variant disrupts the C-terminus of the KAT6B protein. Other variant(s) that disrupt this region (p.Gln1911*, p.Arg1912*) have been observed in individuals with KAT6B-related conditions (PMID: 22077973, 25424711, Invitae). This suggests that this may be a clinically significant region of the protein. For these reasons, this variant has been classified as Pathogenic.
