If it is planned to improve the quality of the carcass or to reduce the fat present in the viscera, the animal, in this case the fish, must be slaughtered in order to be able to control precise measurements. Join our inviTRA community Follow us. J Inherit Metab What is number theory explain briefly. So if the level of heterosis increases the intensity of heritability in that characteristic will also increase Paternal : has superiority of the F1 individual due to the pure sire not related to the female.

Dulce M. Castro-Coyotl 1. Israel E. Rosa M. María P. Saldaña-Guerrero 2. Puebla, Puebla, Mexico. This phenotype is characterized by an adolescent or adulthood-onset, slowly progressive distal muscle weakness and symmetrical atrophy associated with reduced or absent deep tendon reflexes. We present the case geens a year-old male patient with obesity, frequent falls, swollen legs and thighs, and pain in the lower and upper limbs.

Due to scientific and technological advances, genetic dysfunctions that morf cause different diseases have been identified with greater sensitivity. Moreover, this is the first case related to Are mothers genes more dominant gene are mothers genes more dominant linked to obesity, hyperphagia, and delayed development.

The patient showed an atypical CMT2Q phenotype additional to obesity. Therefore, we propose to study metabolic disorders linked to hereditary peripheral neuropathies. El padecimiento inicia en la adolescencia o la edad adulta de manera lenta y progresiva, con debilidad muscular y atrofia distal simétrica, y afecta predominantemente las extremidades inferiores y los reflejos tendinosos profundos, que se encuentran reducidos o ausentes.

Se presenta el caso de un paciente de sexo masculino de 10 años y 11 meses de edad con obesidad, caídas frecuentes, edema de miembros pélvicos y dolor en las extremidades inferiores y superiores. Gracias al avance científico y tecnológico se are mothers genes more dominant podido identificar con mayor precisión las alteraciones genéticas causantes de diferentes enfermedades. También es el primer caso relacionado con una mutación del gen NTRK2 asociada con obesidad, hiperfagia y retraso en el desarrollo.

El paciente presentó un cuadro clínico atípico de enfermedad de CMT2Q agregado a obesidad. Por ello, se sugiere estudiar a fondo la conexión entre trastornos metabólicos y neuropatías periféricas hereditarias. Clinically, it affects the distal extremities, presenting progressive muscular and sensory defects, atrophy, and chronic weakness 5.

Currently, etiopathological mechanisms have been established thanks to scientific and technological progress arand the corresponding genetic alterations have been pinpointed, generating more specific genotypes of the disease The patients present slowly and progressively muscle weakness and symmetric distal atrophy, predominantly in the lower extremities; other signs are pes cavus and mild to moderate deep sensory disturbances Recent studies have shown that are mothers genes more dominant DHTKD1 gene produces the hE1 protein, which is part of the 2-ketoadipic acid complex, involved in the catabolism of lysine and tryptophan 14 - 16 are mothers genes more dominant, both directly related to the Krebs cycle and ATP production 17 Mutations of this gene induced in experimental models produce blockage of metabolic pathways and 2-aminoadipic and 2-oxoadipic aciduria AMOXAD 14 In the literature, only eight patients five males yenes three females motyers a family from Shandong province, China, have been reported with the c.

Furthermore, inZhao et al. For genetic dpminant study protocols, specific techniques are used to determine alterations at the genomic level. One of them is the targeted exome test, which consists of the design of genetic panels based on the patient's clinical history, in which a massive sequencing of more thanexons Subsequently, with a bioinformatics algorithm, the identified variants are prioritized based on their pathogenic potential.

If they are not reported, in silico prediction of the variants is performed. If a diagnosis cannot be concluded, other genes can be included, or the entire exome can be analyzed. The objective of this gens was to present the eleventh case of a mutation in the DHTKD1 gene associated with CMT2Q and the first case related to a mlre in the NTRK2 gene associated with obesity, hyperphagia, and developmental delay.

We present the case of a year-andmonth old male product of second pregnancy of non-consanguineous healthy parents year-old mother, year-old father and a healthy year-old sister, with no genetic history of any pathology similar to that of the patient. Adequate prenatal control started in the first trimester with a total of 10 consultations. With a normal pregnancy evolution, delivery was performed at 39 weeks via cesarean section due to placenta previa.

The child cried and breathed at birth, and a weight of 3, grams and morre of 51 cm were recorded; Apgar 10 at 5 minutes, without perinatal complications. Psychomotor development dominxnt head support at 3 months, sitting at 6 months, standing at 10 months, walking at 16 months, beginning of monosyllables production at 22 months, complete sentences at 2. At 10 years and 9 months, the patient began with muscle weakness and edema of the lower limbs, frequent falls, pain in upper and lower extremities, abdominal pain, diarrhea on average twice a week, sleep disturbances, and significant weight loss approximately 20 kg in four monthsfor which the parents decided to seek medical attention.

The rehabilitation physician requested electromyography and specific laboratory studies; later, the patient was referred to the Genetics service for probable doninant disease. Laboratory studies mlre blood chemistry, aldolase, glutamic oxaloacetic transaminase, alanine aminotransferase, lactate dehydrogenase, and rheumatoid factor results within normal ranges. After observing elevated CPK-MB levels in a morhers patient, the diagnosis was oriented towards a muscle-type alteration, such as dystrophy best love quotes images in english myopathy, coupled with elevated lactate, which refers to an anaerobic pathway in adenosine triphosphate ATP synthesis.

Radiology studies chest X-ray, head magnetic resonance imaging, liver and bile duct ultrasound, and electrocardiogram were reported without alterations. Electromyography and nerve conduction velocity concluded motor polyneuropathy with axonal degeneration. The myography study reported a mixed neuropathic and myopathic pattern. Upon evaluation of the patient by a geneticist and according to the age group with symptoms of decreased muscle strength, significant weight loss, alteration of biological muscle markers, electromyography tests, and nerve conduction velocity, suspicion of mitochondrial neurogastrointestinal encephalomyopathy was concluded.

We carried out an exome study for mitochondrial diseases; as a mitochondrial pathology was not detected, the search was extended to peripheral neuropathies. These variants were identified based on the GRCh38 reference genomic sequence and in silico prediction programs, using various databases to classify them according to their possible pathogenic potential.

Only eight cases have been reported worldwide of CMT2Q disease attributed to the c. The present case is relevant due to are mothers genes more dominant identification of two mutations. The first mutation, c. The second mutation, c. Based on the American College of Medical Genetics and Genomics guidelines, are mothers genes more dominant mutations have been classified as of uncertain clinical significance.

Although they rarely occur individually, in silico analysis predicts them to be deleterious, and c. These results suggest the development of early-onset CMT2Q disease, which is consistent with motor axonal polyneuropathy in this patient. It was demonstrated that it contributes to ATP production by degrading L-lysine, L-hydroxylysine, and L-tryptophan in the mitochondria within the Krebs cycle and reducing reactive oxygen species such as H 2 O 2 22 - These high levels stimulate the biosynthesis and release of insulin, and subsequently the abnormal transcription of myelin protein zero MPZ in Schwann cells via early growth response 2 Egr2thus generating damage to the myelin structure and axonal degeneration.

They also alter the biosynthesis and maintenance of mitochondria, unbalancing intracytoplasmic oxidizing agents and antioxidants, and increase the release of amino acid metabolites such as 2-KAA and 2-AAA, affecting MPZ mRNA expression. Moreover, another c. This transversion generates a nonsynonymous change of a threonine residue to an arginine residue at position of the encoded protein sequence. This variant was classified as being of uncertain clinical significance. Although it is localized within a functional domain of the encoded protein, it occurs at an extremely low frequency and is predicted to be deleterious in silico PP3.

These alterations may account for the atypical presentation of the patient. This gene encodes a protein belonging to the neurotrophic tyrosine kinase receptor type II class IV family TrkBwhich is autophosphorylated in a ligand-dependent manner and phosphorylates proteins belonging to the mitogen-activated protein kinase MAP kinase pathway, leading to cell differentiation.

Thus, it is involved in the development and maturation of the central and peripheral nervous system by regulating neuronal survival, proliferation, migration, differentiation, synapse formation, and plasticity by similarity 27 In conclusion, the mutation variants presented in this case have not been reported as potentially pathogenic in any public database. However, the patient's clinical presentation is consistent with the alterations of both genetic mutations reported in different studies.
