Genetic characterization of main phenotypic cohorts sequenced using the LipidSeq panel
Rare variant | Extreme PS | Overall Genetic Profile | ||||
---|---|---|---|---|---|---|
Rare variant only | Rare variant and an extreme PS | Extreme PS only | No relevant genetic determinants | |||
Familial Hypercholesterolemia N = 924 | 393 (42.5%) | 115 (12.4%) | 354 (38.3%) | 39 (4.2%) | 76 (8.2%) | 455 (49.2%) |
Hypertriglyceridemia N = 1308 | 312 (23.6%) | 428 (32.7%) | 227 (17.4%) | 82 (6.3%) | 346 (26.4%) | 653 (49.9%) |
The “Rare variant” category includes SNVs, indels, and CNVs; these counts include causative and relevant determinants. An extreme polygenic score was defined as being greater than or equal to the 90th percentile, as calculated using the European subgroup of the 1000 Genomes Project (N = 503) [23] The “No related genetic determinants” category refers to patients that had neither a rare variant disrupting a related, canonical metabolism gene, nor an extreme PS. The LDL cholesterol polygenic score calculated in the FH cohort [44] and the triglyceride polygenic score calculated in the hypertriglyceridemia cohort [45] have both been reported previously.
