PKD2 and autosomal dominant polycystic kidney disease: We detected in our proband a previously described nonsense heterozygous PKD2 mutation NM_000297.3:c.2407C>T; p.Arg803Ter (Figure 3a) in exon 13, resulted in a truncated polycystin 2 protein, that was definitely pathogenic (Mayo’s Clinic ADPKD mutation database; http://pkdb.mayo.edu/ and LOVD, HGMD, Clin Var) and reported in different ethnicity (Audrezetet al., 2012; Choi et al., 2014; Chung et al., 2006; Deltas, 2001; Zhang et al., 2005).
