We analyzed twenty fecal samples taken from four premature infants (4-6 time points from each infant), and found significantly higher diametric ratios of genes associated with low oxygen levels in samples of infants later diagnosed with NEC than in samples without NEC. (osti.gov)

It is thought that somatic GNAQ gene mutations that cause isolated port-wine birthmarks occur later in fetal development than those that cause Sturge-Weber syndrome and so affect fewer cells and tissues. (medlineplus.gov)

The spectrum of disease-causing mutations and the associated clinical features of these gene defects are unknown. (nih.gov)
Birth defects, i.e. congenital disorders present at birth, occur in 2%-4% of all neonates [1]. (who.int)

In case only one gene in a pair is recessive, its effect will be marked by its dominant partner, but the recessive gene may still be passed on to the individual's offspring. (jainworld.com)
Obesity is a complex disease that occurs when an individual's weight is higher than what is considered healthy for his or her height. (cdc.gov)

During puberty , differentiation of the male and female body occurs for the purpose of reproduction . (wikipedia.org)
Puberty usually occurs at the normal time, but the testes remain small. (msdmanuals.com)

As cells grow and divide, cells that arise from the cell with the altered gene will have the variant, while other cells will not. (medlineplus.gov)
It's the dialogue among the genes that are writing the sentences, and this finding really writes a very important sentence in the book that we are authoring on uncovering the understanding of how a normal cell functions and why some therapies work or some therapies don't work. (sciencedaily.com)
M2-polarization-related CNTNAP1 gene might be a novel immunotherapeutic target and biomarker for clear cell renal cell carcinoma. (nih.gov)
Importantly, although fate-mapping experiments show both Cxcl12 DsRed+ and Cxcl12 DsRed- cTECs share a common Foxn1 + cell origin, RNA sequencing analysis shows Cxcl12 DsRed- cTECs no longer express Foxn1, which results in loss of the FOXN1-dependent cTEC gene signature and may explain the reduced capacity of Cxcl12 DsRed- cTECs for thymocyte interactions. (ox.ac.uk)
This gene helps repair DNA or kills the cell if it cannot repair the DNA. (medicalnewstoday.com)
When this process does not occur properly, unregulated cell growth may be the end result. (cancerquest.org)
The genes that have been identified to date have been categorized into two broad categories, depending on their normal functions in the cell. (cancerquest.org)
Despite the differences in their normal roles, these genes all contribute to unregulated cell division if they are present in a mutant (oncogenic) form. (cancerquest.org)
