Genetic variation in the FMO2 gene: evolution & functional consequences
PhDFlavin-containing monooxygenase 2 (FMO2) is involved in the metabolism of
xenobiotics, including therapeutic drugs. FMO2 exists in two forms: a functional
and a non-functional form. The functional allele is found only in Africa and
individuals of recent African origin. The aims of the project were to determine
the frequency of functional FMO2 in Africa and obtain insights into the
evolutionary history of the FMO2 gene.
Six hundred and eighty nine samples from nine African population groups
were genotyped for six high-frequency SNPs, and the genetic diversity within
FMO2 was characterized by sequencing 3.44 kb of genomic DNA, encompassing
the entire coding sequence and some flanking intronic sequences in 48 African
individuals. Haplotypes were inferred using Phase and the relationship between
mutations was revealed using reduced-median and median-joining Network. Test
statistics were used to determine whether the genetic variation is compatible with
neutral evolution.
Genotyping indicated that deleterious SNPs occur mostly on a non-functional
allele and that the frequencies of three were significantly different (P<0.05)
among populations. Resequencing identified 32 variants. Genetree was used to
estimate the time to the most recent common ancestral sequence (~0.928 million
years) and the ages of some of the mutations.
Results indicate that the frequency of full-length 23238C alleles is relatively
uniform across sub-Saharan Africa. Interestingly, this is not the case for the
inferred potentially functional 23238C alleles, which frequency differed
significantly (P<0.05) across sub-Saharan Africa.

The results also provide evidence that the frequency of functional FMO2 in
east and west-Africa is high (≥0.54), which has important implications for therapy
with drugs that are substrates for FMO2.
A Ka/Ks > 1, and low nucleotide sequence diversity of intronic regions of
23238C alleles indicate a possible selective sweep.King Saud university of Riyadh Saudi Arabia

TP63-mutation as a cause of prenatal lethal multicystic dysplastic kidneys
BACKGROUND: Ectrodactyly-ectodermal dysplasia-clefting syndrome 3 (EEC) is one of the six overlapping syndromes caused by mutations in the tumor protein p63 gene (TP63). EEC is suspected when patients have cleft hands or feet, polydactyly, and syndactyly, abnormal development of the ectodermally derived structures, and orofacial clefting. Genitourinary (GU) anomalies have been identified in patients with EEC, yet these are often under-recognized and under-reported. The available literature on sonographic prenatal findings is sparse, especially when considering GU anomalies.
METHODS: We present the case of a male stillborn fetus, who was found antenatally to have multicystic dysplastic kidneys and anhydramnios. Following the termination of pregnancy, examination and autopsy further revealed unilateral polydactyly and bilateral syndactyly which had not been previously identified on antenatal ultrasound.
RESULTS: Whole-exome sequencing (WES) revealed a de novo heterozygous pathogenic variant in exon 5 of the TP63 gene: p.His247Arg: c.740A\u3eG (NM_003722.4) which has been reported in the literature. The His247Arg variant has been published as a pathogenic variant in association with EEC, both with and without orofacial clefting.
CONCLUSION: Our prenatal case expands the phenotypic spectrum of TP63-related disorders in general. In addition, it adds to the phenotype associated with the His247Arg pathogenic variant responsible for EEC. Further, we highlight the importance of WES as a postnatal tool to help clarify unexpected findings, and as a way to add to the spectrum of existing phenotypes of known single-gene disorders
Anti-nociceptive effect of gabapentin in mouse models of acute and chronic pain
Purpose: To investigate the anti-nociceptive effect of gabapentin in acute and chronic pain models.
Methods: Four mouse models of pain were used in this study. These comprised thermal tests (hot plate and tail immersion tests), and chemical tests (formalin and acetic acid-induced writhing tests). A total of seventy-two (72) albino mice weighing 25 - 40 g (mean weight = 32.5 ± 5.1 g) were used. In each test, the mice were randomly assigned to three sets of 6 mice each: control group, celecoxib group and drug treatment group. Each test was performed at intervals of 30, 60 and 90 min.
Results: During the acute phase, there was no significant decrease in foot raising (FR) or licking and biting (L & B) episodes among the groups (p > 0.05). However, these episodes were significantly (p < 0.05) decreased in the second delayed phase, in the celecoxib and drug-treated groups, when compared with normal control group. Gabapentin significantly (p < 0.05) decreased pain response throughout the course of the thermal tests. The number of writhes within 30 min were significantly reduced in celecoxib and gabapentin-treated animals, compared with negative control group (p < 0.05). Gabapentin produced approximately 60 % protection of writhing, similar to that produced by celecoxib, the standard non-steroidal anti-inflammatory drug (NSAID) used (61 %).
Conclusion: The results demonstrate that the gabapentin is effective against chronic inflammatory pain in mice and therefore can be potentially developed as an effective anti-inflammatory agent for humans
Measurement of the serum level of Elabela for the early detection of acute kidney injury in hospitalized Iraqi COVID-19 patients
Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is caused coronavirus disease
2019 (COVID-19) affecting people worldwide. The angiotensin converting enzyme2 (ACE2) represents a
receptor of SARS-CoV-2 on the infected host cell. Apelin or its receptor agonists suppress the production of
angiotensin-converting enzyme (ACE) and angiotensin II (Ang-II) and is characterized by a protective effect
against SARS-CoV-2.
Objective: The study aims to assess the serum level of Elabela biomarker as an early detector for Acute
Kidney Injury (AKI) in patients with COVID-19.
Cases and Methods: This is a case-control study which included 45 hospitalized adult patients in multiple
centers (public hospitals) receiving COVID-19 cases in Baghdad. These cases had a positive real-time or
reverse transcription polymerase chain reaction (RT-PCR) of nasal/oropharyngeal swabs. Excluded from the
study were those with a negative PCR and comorbidities and 43 apparently healthy adult subjects as controls.
The age range of the cases and controls was (20 to 60) years
Result: There are no a statistically significant differences between the two groups in terms of age and gender
distribution. Statistically significant differences were found in terms of eGFR, S. Creatinine, D. dimer,
NEU×103
/µL, LYM×103
/µL and ELA biomarker. Significant negative correlations were found between
Elabela with D. dimer and NEU×103
/µL, and between eGFR with S. creatinine, D. Dimer, and NUT×103
/µL.
Conclusion: The Elabela biomarker can be used for the early detection of acute kidney injury in COVID-19
