Clinical Challenges in Diagnosing Primordial Dwarfism: Insights from a MOPD II Case Study.

is a rare group of genetic conditions where individuals experience severe growth restriction, both in the womb and after birth. From as early as the fetal stage, those affected are significantly smaller than their peers. What makes PD distinct is its slow but steady growth pattern, resulting in proportionate dwarfism, where all parts of the body are equally shortened.

Wolfram Syndrome Type I Case Report and Review-Focus on Early Diagnosis and Genetic Variants.

: Wolfram syndrome type 1 (OMIM# 222300; ORPHAcode 3463) is an extremely rare autosomal recessive syndrome with a 25% recurrence risk in children. It is characterized by the presence of juvenile-onset diabetes mellitus (DM), progressive optic atrophy (OA), diabetes insipidus (DI), and sensorineural deafness (D), often referred to by the acronym DIDMOAD. It is a severe neurodegenerative disease with a life expectancy of 39 years, with death occurring due to cerebral atrophy.

The Role of Aminopeptidase ERAP1 in Human Pathology-A Review.

Aminopeptidases are a group of enzymatic proteins crucial for protein digestion, catalyzing the cleavage of amino acids at the N-terminus of peptides. Among them are (coding for endoplasmic reticulum aminopeptidase 1), (coding for endoplasmic reticulum aminopeptidase 2), and (coding for leucyl and cystinyl aminopeptidase). These genes encoding these enzymes are contiguous and located on the same chromosome (5q21); they share structural homology and functions and are associated with immune-mediated diseases.

A New Frameshift Mutation of Gene Associated with Cowden Syndrome-Case Report and Brief Review of the Literature.

Cowden syndrome (CS) is a rare disease that was first described in 1963 and later included in the large group of genodermatoses. It is the most common syndrome among the -associated hamartomatous tumor syndromes (PHTS). CS has an autosomal dominant inheritance pattern, with increased penetrance and variable expressivity, making early diagnosis difficult.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant neurocutaneous syndrome. It is manifested mainly in cutaneous lesions, epilepsy and the emergence of hamartomas in several tissues and organs. The disease sets in due to mutations in two tumor suppressor genes: and .

Effects of Burosumab Treatment on Two Siblings with X-Linked Hypophosphatemia. Case Report and Literature Review.

X-linked hypophosphatemia (XLH) or vitamin D-resistant rickets (MIM#307800), is a monogenic disorder with X-linked inheritance. It is caused by mutations present in the Phosphate Regulating Endopeptidase Homolog X-Linked (PHEX) gene responsible for the degradation of the bone-derived hormone fibroblast growth factor 23 (FGF23) into inactive fragments, but the entire mechanism is currently unclear. The inactivation of the gene prevents the degradation of FGF23, causing increased levels of FGF23, which leads to decreased tubular reabsorbtion of phosphorus.

The Treatment with Interleukin 17 Inhibitors and Immune-Mediated Inflammatory Diseases.

IL-17 inhibitors (IL-17i) are medicines used to treat dermatological and rheumatic diseases They belong to a class of medicines called biological disease-modifying anti-rheumatic drugs (bDMARDs). This class of drugs has had a major impact on the therapy of autoimmune diseases, being much safer and more effective than treatment with small molecules. At the same time, they have highly beneficial effects on skin and joint changes, and their efficacy has been extensively monitored and demonstrated in numerous clinical trials.

Changes in skeletal dysplasia nosology.

Skeletal dysplasia (SD), also called osteochondrodysplasia (OCD), is a large group of skeletal disorders (over 400 distinct entities) caused by abnormalities in bone development and growth. SDs varies according to different natural histories, prognoses, hereditary patterns to etiopathogenetic mechanisms. At birth, the incidence is low, reported at the level of each entity, but taken collectively; the incidence is estimated at 1:5000 births.

Cardiofaciocutaneous syndrome - a longitudinal study of a case over 33 years: case report and review of the literature.

Cardiofaciocutaneous (CFC) syndrome [Online Mendelian Inheritance in Man (OMIM) #115150] is characterized by craniofacial dysmorphism, heart malformation, ectodermal abnormalities, neuromotor delay and intellectual disability. It is not a frequent disease, about 300 cases have been reported in the medical literature. We describe the case of a 34-year-old patient presenting with CFC syndrome phenotype, monitored since the age of 1 1∕2 years.

Greig Cephalopolysyndactyly Contiguous Gene Syndrome: Case Report and Literature Review.

Greig cephalopolysyndactyly syndrome (GCPS) is a rare genetic disorder (about 200 cases reported), characterized by macrocephaly, hypertelorism, and polysyndactyly. Most of the reported GCPS cases are the results of heterozygous loss of function mutations affecting the gene (OMIM# 175700), while a small proportion of cases arise from large deletions on chromosome 7p14 encompassing the gene. To our knowledge, only 6 patients have been reported to have a deletion with an exact size (given by genomic coordinates) and a gene content larger than 1 Mb involving the gene.

Genetics of congenital solid tumors.

When we discuss the genetics of tumors, we cannot fail to remember that in the second decade of the twentieth century, more precisely in 1914, Theodore Boveri defined for the first time the chromosomal bases of cancer. In the last 30 years, progresses in genetics have only confirmed Boveri's remarkable predictions made more than 80 years ago. Before the cloning of the retinoblastoma 1 (RB1) gene, the existence of a genetic component in most, if not all, solid childhood tumors were well known.

Demographic data, clinical, paraclinical investigations and outcome were registered and analyzed.

Treatment of Epilepsy Associated with Common Chromosomal Developmental Diseases.

Chromosomal diseases are heterogeneous conditions with complex phenotypes, which include also epileptic seizures. Each chromosomal syndrome has a range of specific characteristics regarding the type of seizures, EEG findings and specific response to antiepileptic drugs, significant in the context of the respective genetic etiology. Therefore, it is very important to know these particularities, in order to avoid an exacerbation of seizures or some side effects.

Choroidal melanoma, unfavorable prognostic factors. Case report and review of literature.

Uveal melanoma is the most common intraocular tumor characterized by increased metastatic potential. The tumor develops from uveal melanocytes that, from an embryological point of view, derive from the cells of the anterior neural crest. The risk factors associated with melanoma development are close related to patient phenotype: light-colored hair and iris, fair skin.
