Department of Pathology and Laboratory Medicine, Sinai Health System RCV000904777 SCV001552920 uncertain significance not provided no assertion criteria provided clinical testing The AHDC1 p.Gly559Ser variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs765994795) and in 15 of 279008 chromosomes at a frequency of 0.000054 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 7 of 7104 chromosomes (freq: 0.000985) and European (non-Finnish) in 8 of 126874 chromosomes (freq: 0.000063); it was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish) and South Asian populations. The variant occurs outside of the splicing consensus sequence however 2 of 4 (SpliceSiteFinder-like and MaxEntScan) in silico or computational prediction software programs (SpliceSiteFinder-like and MaxEntScan) predict the gain of a 3' splice site at c.1676 and SpliceSiteFinder-like also predicts the loss of a 5' splice site at c.1675; however, this is not very predictive of pathogenicity. The p.Gly559 residue is conserved in mammals however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
