RCV000866494 | SCV001552083 | uncertain significance | not provided | no assertion criteria provided | clinical testing | The SMAD3 p.Gly249Gly 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: rs769683236) and in control databases in 19 of 282784 chromosomes at a frequency of 0.000067 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 1 of 7228 chromosomes (freq: 0.000138), European (non-Finnish) in 16 of 129092 chromosomes (freq: 0.000124), South Asian in 1 of 30616 chromosomes (freq: 0.000033) and Latino in 1 of 35440 chromosomes (freq: 0.000028); it was not observed in the African, Ashkenazi Jewish, East Asian, and European (Finnish) populations. The p.Gly249Gly variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence however 3 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, and NNSPLICE) predict a greater than 10% difference in splicing and the creation of a new 5' splice site. However, this information is not predictive enough to assume 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. |
