The variant was identified in the following databases: dbSNP (ID: rs146430229) as With Likely benign allele, ClinVar (classified as likely benign by Prevention Genetics), and ADPKD Mutation Database (classified as likely neutral). The variant was identified in control databases in 145 of 267766 chromosomes at a frequency of 0.000542 in the following populations: European in 126 of 122526 chromosomes (freq. 0.001), Latino in 10 of 34254 chromosomes (freq. 0.0003), African in 5 of 23542 chromosomes (freq. 0.0002), Other in 2 of 6342 chromosomes, increasing the likelihood this could be a low frequency variant (Genome Aggregation Consortium Feb 27, 2017). The c.12139-5C>T variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. However, positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. However, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign.
