However, the aldoaa and kif22 genes each showed a robust phenotype at 50% LOF, which might indicate the effects of genetic hemizygosity at these loci, and designate these genes as putative deletion dosage sensors.
When building these structures, defects including lack-of-fusion (LOF) at interlayer boundaries and intralayer porosity are sometimes observed.
Possessing at least one LOF, of a data point, nearly equal to 1.0 but greater than 1.0, ensures that all less dense data points and outliers are included in border points.
To more precisely characterize the effect of pros LoF at the cellular level, we generated null-mutant MARCM NB clones in the developing postembryonic brain using prosv17.
A conservative estimate suggests that there are at least 250 LOF variants per sequenced genome, 100 of them involved in known human diseases, and more than 30 in a homozygous state, which suggests a previously unnoticed level of variation with putative functional consequences in protein coding regions in humans [ 16].
Median age at diagnosis in LoF carriers was very similar to non-carriers: 58.5 and 59.0 years, respectively (P=0.334), and median presenting PSA was higher in carriers compared with non-carriers but the difference was not significant (11.10 vs 8.25 ng ml−1, P=0.156).
Further analysis showed that compared with subjects who were WT at all six SNP positions (n=84), subjects who had a LOF SNP at either c.151+1G>T, c.G946A, c.1096C>G, c.1513A>C or c.1729T>A (n=48) had almost ninefold greater annualised percent change from baseline in LS BMD (−0.9354%/year for the LOF group and −0.1057%/year for the WT group, P=0.0005).
For phospholipidosis Ball and LOF demonstrated similar performance, though LOF is a bit more efficient.
The total LOF scores at baseline (unadjusted) and each subsequent 3-month follow-up visit (LS means) are shown in Figure 4.
Recently, Charlier et al. [ 17] showed that LoF variants at the homozygous state can compromise fertility in cattle by causing embryonic lethality [ 17].
