Clinical Validity Scoring Notes and points

Congenital heart disease:

Li 2018 PMID: 30322850 - Per supp1 - there are 4 variants identified in probands with congenital heart defects. Variants found via exome sequencing, but unclear whether they were inherited or de novo, or parents tested at all. (1) c.G711C p.Q237H - absent gnomad, REVEL score 0.165, in patient with PDA. (2) c.T811G p.W271G - absent gnomAD, REVEL score 0.643 proband with VSD, ASD, PDA. (3) c.933_934 ins AA p.T312K fs*55 - NMD+ truncating variant, absent gnomAD, in proband with ASD and pulmonary stenosis. (4) c.A1558C p.S520R - absent gnomAD, REVEL 0.213. There was some functional evidence, but I didn’t take the time to score these variants; congenital heart defects are too common to score any of these variants with points.

TAN 2022 PMID: 35910219 - c.813G > A (p.Trp271*) - Absent gnomAD, NMD+ truncation. Found het in case 20B10556859; I don’t see where the patient phenotype is described in any specifics (including the supplement) except that this is a congenital heart disease cohort.
