Fourteen were previously unreported mutations, bringing the total number of different keratin mutations associated with PC to 105.
Forty-six distinct keratin mutations were found, 14 of which were previously unreported mutations, bringing the total number of different keratin mutations associated with PC to 105.
The four mutations brought the CRP site close (to within two mutations) to its consensus sequence [ 24], which we assumed would enhance the ability of CRP to activate expression.
In the PpcAM58D mutant, the mutation brings the midpoint reduction potential values of all haem groups closer to each other (cf. broken and continuous lines on Figure 5).
Thus, a balance between mutation and purifying selection can in principle explain the maintenance of lagging strand encoded genes, and the probability for a gene to be encoded on the lagging strand is determined by the ratio between the relative disadvantage of lagging strand encoding and the rate of mutation bringing the gene from the leading to the lagging strand.
Analysis of exome-sequencing data from a follow-up series of overgrowth probands identified a further pathogenic mutation, bringing the total number of affected individuals to 5. Heterozygotes shared similar phenotypic features including increased height, increased head circumference and intellectual disability.
In GAS, frameshift mutations followed by compensatory mutations that bring the gene back into frame are proposed to play a role in antigenic variation of M proteins [62], a scenario that may play out over time in 02161A to generate a novel sim allele.
Random mutations thus accumulate in HSCs during repeated replications unless the mutations bring on a loss of stem cell function.
More likely, these mutations bring about changes in protein protein interactions, changes in localization of diguanylate cyclases in the cell, or alterations in the relative orientation of domains.
What other effects do Jo's unusual genetic mutations bring?
