Variant summary: The APC c.6387G>A (p.Ser2129Ser) variant causes a synonymous change involving a non-conserved nucleotide, 4/5 splice prediction tools predict no significant impact on normal splicing, although these predictions have yet to be functionally assessed. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 34/121086 (1/3561), predominantly in the Latino cohort, 30/11544 (1/384), which significantly exceeds the estimated maximal expected allele frequency for a pathogenic APC variant of 1/14005. Therefore, suggesting this is likely a benign polymorphism found primarily in population(s) of Latino origin. The variant of interest has not been, to our knowledge, reported in affected individuals via publications, although multiple clinical diagnostic laboratories cite the variant with a classification of "likely benign/benign." Therefore, the variant of interest has been classified as Benign.
