Parental influence on human germline de novo mutations in 1,548 trios from Iceland

DNA mutations (alteration of a nucleotide base) can occur in the germline or somewhere in the body other than the germ cells (spermatozoa and ova). The former are called germ cell mutations, and the latter somatic cell mutations. It has … Continue reading

Gene-environment interaction study of body mass index (BMI) reveals interactions between genetic factors and physical activity, alcohol consumption, and socioeconomic status

Genome-wide association studies (GWAS) are used for attempting to find genes/genetic loci associated with a phenotype (trait). The trait chosen to be studied might be height, weight or body mass index (BMI) –– or a complex disease such as schizophrenia, … Continue reading

CRISPR/Cas9-edited correction of an autosomal dominant gene mutation responsible for hypertrophic cardiomyopathy (cause of sudden death in otherwise healthy young athletes)

The CRISPR/Cas9-edited correction of an autosomal dominant gene mutation (2 August 2o17 Nature paper –– reported by GEITP Sept 7; see way below and attached pdf files) now seems to be questioned by a number of other researchers in the … Continue reading

Predatory journals are even able sometimes to scam some senior scientists who should know better

GEITP emailings have frequently covered this topic of “predatory” “online, open-access” journals that have exploded in the past few years and now number more than 8,000 (some estimates are as high as 15,000). Pseudoscientific “editors” and “publishers” of predatory journals … Continue reading

Genome-wide association study (GWAS) of gestational duration and spontaneous preterm birth

“Preterm birth” is defined as “birth at less than 37 completed weeks of gestation”. Prematurity used to be viewed as an “unpredictable and inevitable fact of life”. Medical efforts have thus focused on improving the consequences of prematurity rather than … Continue reading

Prevention of newborn infections and systemic sepsis by using probiotics in an India rural population

“Sepsis” is a clinical syndrome characterized by systemic inflammation and circulatory compromise initiated by an infection. For those of us who have experienced working in newborn and premie nurseries, especially in county hospitals or rural settings, we know well that … Continue reading

CRISPR/Cas9-edited correction of an autosomal dominant gene mutation responsible for hypertrophic cardiomyopathy (cause of sudden death in otherwise healthy young athletes)

This is a follow-up of the layman’s article that GEITP previously shared on Aug 3 [from The New York Times, see below]. To reiterate, autosomal dominant mutations are inherited (from parent to child) as a single copy of a defective … Continue reading
