Number of variants

Trio exome sequencing

111,596

Annotation and filtering with Ensembl VEP

Filter 1: AF <2 % in population subcohorts, <5 x homozygous occurrences in gnomAD exomes v2.1.1

7,031

Filter 2: VEP impact HIGH or MODERATE or SpliceAI score >0.1

841

Prioritization

1) Variants in candidate genes of phenotypic relevance

92

2) Variants segregating in compliance with a Mendelian Disease (full penetrance)

65

Variants shared between (1) and (2) (these variants can be found in Supplementary Data 1)

7 (genes: TTN (2x), DNM1L, TBK1, TNFRSF13B, and RUNX1 (2x))

Variants considered relevant to the severe COVID-19 disease course
