Ethionamide treatment instead may cause hypothytoidism as in developing children as in adults and the risk is higher for children on regimens including para-aminosalycilic acid and for HIV-infected children [ 113].
Small size is not always related to the GH/IGF/MTOR pathway but instead may be caused by defects that shorten life span.
Some of the risk alleles studied here may not be disease causing, but instead may be in linkage disequilibrium (LD) with the disease causing allele.
Changes in DTNBP1 expression are probably not caused by antipsychotic drug treatment [ 47] but instead may reflect an increased genetic vulnerability for schizophrenia.
Thus, the excess of X-linked, female-biased genes may not be related to dosage compensation, but instead may reflect an overall feminization of the X chromosome [ 60], possibly caused by sexually antagonistic selection [ 21, 62, 63].
Alternatively, they may simply not be paralogs but instead may result from cryptic-speciation.
Therefore, even small levels of uncertainty do not simply imply kinks in the demand function as in Iyengar, Jedidi, and Kohli; instead, they may cause actual discontinuities in the demand functions (cf. Moffitt 1986, p. 320), because demand is shifted to a different tariff segment.
The bow has nowhere to release its energy, and it goes into the limbs instead, which may cause it to crack.
We hypothesized that wear debris may not be responsible for the loosening and failure of ceramic-on-ceramic implants but, instead, that mechanical problems may cause instability of the implants and result in production of wear debris.
Species may be incompletely isolated due to recent or incomplete speciation, the pattern of speciation may not be a simple cladogenetic event but may be instead paraphyletic, hybridization may cause reticulate evolution, and sorting of ancestral polymorphisms may render gene trees incongruent with species trees [17], [38] [40].
