The frequency of carriers is 0.00076. As the frequency is low,
we may neglect the frequency of homozygous carriers and thus 
consider that only heterozygous carriers are observed. Given
the frequency of disease allele is q, the frequency of 
carriers is
		2 q (1-q) = 0.00076
Neglecting q^2 term,
		2 q = 0.00076 => q = 0.00038
Given the slection pressure is 0.7 (it is one minus survival), 
from formula
		q^2 = mu/s
we may find mu
		mu = s q^2
		mu = 0.7 * 0.00038 * 0.00038 = 1.0108E-007
