1. When do we need to suspect maturity onset diabetes of the young in patients with type 2 diabetes mellitus?
ABSTRACT Objetivo: Maturity onset diabetes of the young (MODY) patients have clinical heterogeneity as shown by many studies. Thus, often it is misdiagnosed to type 1 or type 2 diabetes(T2DM). The aim of this study is to evaluate MODY mutations in adult T2DM patients suspicious in terms of MODY, and to show clinical and laboratory differences between these

2. Genetics of COVID-19
Abstract Objective This narrative, non-systematic review provides an update on the genetic aspects of the SARS-CoV-2 virus and its interactions with the human genome within the context of COVID-19. Although the main focus is on the etiology of this new disease, the genetics of SARS-CoV-2 impacts prevention, diagnosis, prognosis, and the development of thera

4. The effect of mutation status, pathological features and tumor location on prognosis ın patients with colorectal cancer
SUMMARY OBJECTIVE: Colorectal cancer is the most common malignancy of the gastrointestinal tract. It is the third most common tumor in both genders and the second reason of cancer-related deaths. In recent years, tumor location has gained importance as a prognostic indicator. In this study, we aimed to analyze if there was a prognostic effect of tumor locat

5. Fabry disease: genetics, pathology, and treatment
SUMMARY Fabry disease (FD) is a recessive monogenic inheritance disease linked to chromosome X, secondary to mutations in the GLA gene. Its prevalence is estimated between 1:8,454 and 1:117,000 among males and is probably underdiagnosed. Mutations in the GLA gene lead to the progressive accumulation of globotriaosylceramide (Gb3). Gb3 accumulates in lysosome

6. Evaluating the current state of the art of Huntington disease research: a scientometric analysis
Huntington disease (HD) is an incurable neurodegenerative disorder caused by a dominant mutation on the 4th chromosome. We aim to present a scientometric analysis of the extant scientific undertakings devoted to better understanding HD. Therefore, a quantitative study was performed to examine the current state-of-the-art approaches that foster researchers’

7. The clinical genetics of phaeochromocytoma and paraganglioma
ABSTRACT Phaeochromocytoma and paraganglioma are rare catecholamine-producing tumours, recognised to have one of the richest hereditary backgrounds of all neoplasms, with germline mutations seen in approximately 30% of patients. They can be a part of genetic syndromes such as MEN 2 or Neurofibromatosis type 1, or can be found as apparently sporadic tumours.

8. Prevalence of scoliosis in Williams-Beuren syndrome patients treated at a regional reference center
OBJECTIVE:This study assessed the prevalence of scoliosis and the patterns of scoliotic curves in patients with Williams-Beuren syndrome. Williams-Beuren syndrome is caused by a chromosome 7q11.23 deletion in a region containing 28 genes, with the gene encoding elastin situated approximately at the midpoint of the deletion. Mutation of the elastin gene leads

9. Cochlear function in ultra-high frequencies in parents of individuals with autosomal recessive hearing loss / Função coclear em frequências ultra-altas em pais de indivíduos com deficiência auditiva autossômica recessiva
INTRODUCTION: In nonsyndromic hearing loss of recessive autosomal heritage, caused by changes in the gene GJB2 (Gap Junction Bet-2 Protein), parents of individuals with hearing loss are heterozygous carriers of a recessive allele which causes deafness, however, are asymptomatic, but may present early and mild hearing changes. OBJECTIVE: Assessing the cochlea

10. Estudo da etiologia da perda auditiva em amostra de individuos brasileiros : diretrizes para protocolo de conduta clínica / Study of the etiology of hearing loss in a sample of brazilian individuals : guidelines for clinical management protocol
Deafness is considered the most prevalent sensory disorder in humans, caused by a variety of environmental and genetics factors. In Brazil, there are no official data regarding the prevalence and etiology of hearing impairment, but it is known that environmental factors are among the major causes. Although a simultaneous testing approach, including clinical

11. Análise dos genes GHRH e GL12 em pacientes com deficiência de hormônio do crescimento congênita / GHRH and GLI2 genes analysis in patients with congenital growth hormone deficiency
Introduction: Alterations in genes related to GH secretion and pituitary organogenesis have been identified in patients with congenital GH deficiency (GHD). However, in only few cases of GHD the etiology has been established. GH-releasing hormone (GHRH) is an obvious candidate to explain isolated GH deficiency (IGHD). Previous reports in the literature did n

12. Determinantes genéticos na síndrome de Noonan e nas síndromes Noonan-like: investigação clínica e molecular / Genetic determinants in Noonan syndrome and in Noonan-like syndromes: clinical and molecular study
A síndrome de Noonan (SN) é uma doença de herança autossômica, relativamente frequente na população e que apresenta heterogeneidade genética. Caracteriza-se por dismorfismos faciais, baixa estatura, pescoço curto/alado, alterações cardíacas, deformidades esternais e criptorquia. A SN apresenta sobreposição dos achados clínicos com outras sínd
