Neuberg Centre For Genomic Medicine, NCGM RCV004785796 SCV005400835 uncertain significance AHDC1-related intellectual disability - obstructive sleep apnea - mild dysmorphism syndrome 2023-06-22 criteria provided, single submitter clinical testing The missense variant c.1481A>G(p.Lys494Arg) in AHDC1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The observed variant is absent in gnomAD exomes database. This variant has not been submitted to the ClinVar database. Multiple lines of computational evidence (Polyphen - probably damaging, SIFT - damaging and MutationTaster - disease causing) predict a damaging effect on protein structure and function for this variant. The reference amino acid change p.Lys494Arg in AHDC1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Lys at position 494 is changed to a Arg changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Uncertain Significance (VUS).
