MYBPC3 truncating variants in HCM cohorts

The table below lists the 566 rare (MAF<0.0001 in ExAC) truncating MYBPC3 variants identified in a cohort of 6179 HCM patients (3267 patients from OMGL, 2912 patients from LMM). When this rare variant frequency of 0.09160 is compared with a background population rate of 0.00086, there is a statistically significant case excess of 0.09074 (p<0.0001), which suggests that approximately 560 of these variants may be pathogenic.

Variant Type: All protein-altering variants - Truncating variants - Non-Truncating variants

Source: Combined (OMGL + LMM) - OMGL - LMM
