Nonclassic lipoid congenital adrenal hyperplasia masquerading as familial glucocorticoid deficiency [PDF]

open access: yes, 2009
Context: Familial glucocorticoid deficiency (FGD) is an autosomal recessive disorder resulting from resistance to the action of ACTH on the adrenal cortex.

Interplay Between Capsule Expression and Uracil Metabolism in Streptococcus pneumoniae D39

open access: yesFrontiers in Microbiology, 2018
Pyrimidine nucleotides play an important role in the biosynthesis of activated nucleotide sugars (NDP-sugars). NDP-sugars are the precursors of structural polysaccharides in bacteria, including capsule, which is a major virulence factor of the human ...

8-oxoguanine causes spontaneous de novo germline mutations in mice. [PDF]

open access: yes, 2014
Spontaneous germline mutations generate genetic diversity in populations of sexually reproductive organisms, and are thus regarded as a driving force of evolution. However, the cause and mechanism remain unclear.

Genetic screening for SACS, ABHD12 and PRICKLE1 mutations in ataxia patients from Southern Italy [PDF]

open access: yes, 2011
Genetic screening for SACS, ABHD12 and PRICKLE1 mutations in ataxia patients from Southern Italy. INTRODUCTION Autosomal recessive (AR) spinocerebellar ataxias constitute a heterogeneous group of neurodegenerative disorders mainly characterized by ...

Clinical, genetic, and functional characterization of four patients carrying partial loss-of-function mutations in the steroidogenic acute regulatory protein (StAR) [PDF]

open access: yes, 2010
Context: Nonclassic congenital lipoid adrenal hyperplasia (lipoid CAH) is a recently recognized disorder caused by mutations in the steroidogenic acute regulatory protein (StAR) that retain partial function.

Experimental evolution of gene essentiality in bacteria

open access: yesmBio
Essential gene products carry out fundamental cellular activities in interaction with other components. However, the lack of essential gene mutants and appropriate methodologies to link essential gene functions with their partners poses significant ...

Molecular Clock of Neutral Mutations in a Fitness-Increasing Evolutionary Process. [PDF]

open access: yesPLoS Genetics, 2015
The molecular clock of neutral mutations, which represents linear mutation fixation over generations, is theoretically explained by genetic drift in fitness-steady evolution or hitchhiking in adaptive evolution.

Autoimmunity as the Consequence of a Spontaneous Mutation in Rasgrp1 [PDF]

open access: yesImmunity, 2012
A mouse strain was identified with a recessive genetic lesion, which spontaneously developed a lymphoproliferative autoimmune syndrome exhibiting features of systemic lupus erythematosus. Positional mapping of the disease-associated locus revealed a lesion in Rasgrp1 that prevented the translation of the RasGRP1 protein.

Folliculin mutations are not associated with severe COPD

open access: yesBMC Medical Genetics, 2008
Background Rare loss-of-function folliculin (FLCN) mutations are the genetic cause of Birt-Hogg-Dubé syndrome, a monogenic disorder characterized by spontaneous pneumothorax, fibrofolliculomas, and kidney tumors.

Diazoxide-responsive hyperinsulinemic hypoglycemia caused by HNF4A gene mutations [PDF]

open access: yes, 2010
Objective: The phenotype associated with heterozygous HNF4A gene mutations has recently been extended to include diazoxide responsive neonatal hypoglycemia in addition to maturity-onset diabetes of the young (MODY).
