GeneDx RCV000484799 SCV000568477 pathogenic not provided 2017-02-20 criteria provided, single submitter clinical testing The c.6553delG known pathogenic variant has been observed previously in several families with Hereditary Breast and Ovarian Cancer (Kim 2012, Kang 2015, Ogata 2015). This deletion causes a frameshift starting with codon Alanine 2185, changes this amino acid to a Leucine residue, and creates a premature Stop codon at position 6 of the new reading frame, denoted p.Ala2185LeufsX6. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. The c.6553delG variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Therefore, based on the ACMG recommendations, c.6553delG is interpreted as a known pathogenic sequence change.
