Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. p.Lys12fsX156, p.Ser275fsX38). The variant was absent in 242874 control chromosomes (gnomAD). c.33delC has been reported in the literature in homozygous individuals affected with Primary Hyperoxaluria Type 1 (Amoroso 2001, Williams 2007, Hoyer-Kuhn_2014). These data indicate that the variant is likely to be associated with disease. One of these publications also measured liver AGT activity in a homozygous patient, and demonstrated a pronounced variant effect, resulting in <10% of normal activity (Williams 2007). No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic.
