Comment:

This frameshifting variant in exon 1 of 2 introduces a premature stop codon and is therefore predicted to result in loss of normal protein function. This variant has been previously reported as a de novo change in a patient with alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) (PMID: 23505205). It is absent from the ExAC and gnomAD population databases and thus is presumed to be rare. Analysis of the parental samples was negative for the variant, indicating this variant likely occurred as a de novo event. Based on the available evidence, the c.691_698delGCGGCGGC (p.Ala231ArgfsTer61) variant is classified as pathogenic.

Comment:

This frameshift variant results in a premature stop codon, likely leading to nonsense-mediated decay and lack of protein production. It has been reported to be de novo in a patient presenting with alveolar capillary dysplasia with misalignment of pulmonary veins. This variant is absent from a large population dataset. It has a ClinVar entry. We consider this variant to be pathogenic.

Comment:

Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 23505205, 31641027, 31436901, 32036090, 33578219, 31199666)
