The C11orf80 p.Ala56Pro variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs1354765930) and in control databases in 14 of 251440 chromosomes at a frequency of 0.00005568 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the East Asian population in 14 of 18394 chromosomes (freq: 0.000761), but was not observed in the African, Latino, Ashkenazi Jewish, European (Finnish), European (non-Finnish), Other, or South Asian populations. The p.Ala56 residue is conserved in mammals and 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. The variant occurs outside of the splicing consensus sequence and 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this 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. -
