Mutations in the bone morphogenetic protein 15 gene causing defective protein secretion in Cholistani infertile sheep

Braz. j. biol; 84 (), 2024
Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding ...

Relatam-se três casos de pacientes do sexo feminino, acompanhadas em hospital universitário, com pápulas e nódulos eritêmato-acas- tanhados dolorosos em membros superiores e tórax, agravados por frio...

Novel Pathogenic Mutation Mapping of ASPM Gene in Consanguineous Pakistani Families with Primary Microcephaly

Braz. j. biol; 83 (), 2023
Abstract Autosomal recessive primary microcephaly (MCPH) is a neurodevelopmental disorder characterized by a congenitally reduced head circumference (-3 to -5 SD) and non-progressive intellectual disability. The objective of the study was to evaluate pathogenic mutations in the ASPM gene to understand et...

Two non-familial cases of Galloway-Mowat syndrome carrying the homozygous mutations of WDR73 and TP53RK

Galloway–Mowat syndrome (GAMOS) is a rare hereditary disease manifested as a combination of nephrotic syndrome and central nervous system impairment. To date, many GAMOS cases attributed to various gene mutations have been reported such as WHAMM, NUP107, WDR73, OSGEP, and TP53RK. We detected two novel ...

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 ...

Central nervous system high-grade neuroepithelial tumor with BCOR alteration: a short report

Clin. biomed. res; 42 (1), 2022
Central nervous system high-grade neuroepithelial tumors with BCOR alteration are rare. Currently, there are only 24 cases reported in the literature. These tumors are characterized by a change involving the BCOR gene and have a poor prognosis. Studies are needed to improve the current therapy and outcom...

Acetilación N-terminal, acetiltransferasas y mutaciones en subunidad auxiliar NAA15 de N-terminal acetiltransferasa A, asociadas a discapacidad intelectual y trastorno del espectro autista: una revisión bibliográfica

Rev. ANACEM (Impresa); 16 (2), 2022
Las N-terminal acetiltransferasas (NaT) son fundamentales en el desarrollo, funcionamiento y vida media celular, acetilando gran parte del proteoma humano. Entre las ocho NaT identificadas, N-terminal acetiltransferasa A (NaTA) acetila a un mayor número de sustratos, teniendo además un rol fundamental ...

Familial amyloid polyneuropathy: a proposal for an epidemiological study through the creation of a virtual platform

Rev. bras. neurol; 57 (3), 2021
Amyloidosis are characterized by mutations in the gene coding for transthyretin (TTR), located on chromosome 18. TTR is a set of four 127-aminoacid polypeptides structured as homotetrameric protein of 56 kDa with a secondary ß sheet structure. It plays the role of thyroxin (T4) carrier, and has a bindin...

Afectación respiratoria en paciente con acrodisostosis: una asociación infrecuente de una enfermedad rara

Arch. argent. pediatr; 119 (4), 2021
La acrodisostosis es una displasia esquelética rara, de herencia autosómica dominante, que se caracteriza por la presencia de disostosis facial y periférica, talla baja y diferentes grados de obesidad. La acrodisostosis de tipo 1, secundaria a la mutación heterocigota en el gen PRKAR1A (17q24.2), se ...
