highly significantP = 3.8 × 10 −10
We perform whole-exome or genome sequencing of 146 kindreds with sporadic (n = 138) or familial (n = 8) CFM, identifying a highly significant burden of loss of function variants in SF3B2 (P = 3.8 × 10 −10 ), a component of the U2 small nuclear ribonucleoprotein complex, in probands.
