The c.491_492delTG pathogenic variant in the PRKAR1A gene has been reported previously in association with Carney complex (Kirschner et al., 2000; Bertherat et al., 2009; Guo et al., 2015). The deletion causes a frameshift starting with codon Valine 164, changes this amino acid to a Aspartic Acid residue and creates a premature Stop codon at position 5 of the new reading frame, denoted p.Val164AspfsX5. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense mediated mRNA decay. Therefore, we interpret this variant as pathogenic.
