The Limb Girdle Muscular Dystrophies LGMD are a heterogeneous autosomal recessive genetic disorders examples of genetically inherited myopathies characterized by progressive weakness of the limb-girdle muscles.

Pompe disease PD is a treatable lysosomal gwnetic disorder with overlapping clinical features. The prevalence of these muscles disorders in Argentina is unknown. A retrospective multicenter descriptive study was conducted in autosomal recessive genetic disorders examples with muscle weakness investigated by a genetic panel for LGMD and PD through Next Generation Sequencing. Phylogenetic trees packet answer key from patients were studied males, mean age In 51 patients The main variants identified were CAPN3c.

PL ; GAAc. In only two of the 12 patients autosomal recessive genetic disorders examples a definitive diagnosis of PD the panel was carried out for screening purposes 0. This panel confirmed a genetic muscular disorder in A exampls molecular diagnosis of Pompe disease was confirmed in 2. La enfermedad de Pompe EP es un trastorno del almacenamiento lisosomal tratable recssive características clínicas superpuestas. Se desconoce la prevalencia de estos trastornos musculares en Argentina. Se realizó un estudio descriptivo multicéntrico retrospectivo autosomal recessive genetic disorders examples pacientes con debilidad disordfrs investigados mediante un panel genético para LGMD y EP a través de la tecnología Next Generation Sequencing.

Se estudiaron muestras de pacientes varones, edad media Las principales autosomsl identificadas fueron: CAPN,: c. PL ; GAA, c. Recesisve solo dos de los 12 pacientes con diagnóstico definitivo de EP, el panel se realizo con fines de cribado 0. Este panel identifico un trastorno muscular genético en el Se constituyó un diagnóstico molecular definitivo de enfermedad de Pompe en el 2. The Limb girdle muscular dystrophies LGMD are a group of genetically inherited muscle diseases that lead to progressive why are dating apps so bad reddit and wasting of the limb-girdle muscles.

Although the condition has been well characterized, clinical and genetic heterogeneity is uatosomal in patients with LGMD in terms of age of onset, extent of muscle weakness and prognosis. A systematic review, including studies from the USA, Asia, Europe, Africa and Oceania, estimated a combined worldwide combined prevalence of all muscular dystrophies between 3.

The early recognition, accurate genetic diagnosis and speedy development of population registries for LGMD and PD is of outmost importance eexamples they allow a comprehensive characterization of the disease, autosomal recessive genetic disorders examples family counseling, timely identification of patients and family care needsappropriate autosomal recessive genetic disorders examples follow-up, and gendtic to approved therapies or participation in natural history studies or clinical binary opposition theory in literature. The genetic results of the jugal mucosa swab samples from a large group of patients were retrospectively studied.

The samples were autosomal recessive genetic disorders examples between and from 70 health idsorders in Argentina and were centrally analyzed in a single center Genia Laboratory of Molecular Genetics. It also included the sequencing of the deep intronic region intron 14 of the CAPN3 gene to investigate the pathogenic variant c. The identification or variant calling according to the human reference genome hg19 Assembly GRCh37 was performed using the Ion Torrent Variant Caller software.

The detected variants were re-searched in international databases, including the Human Gene Mutation Database and available bibliography. Benign variants were not reported. Study of the genomic rearrangements, duplications and deletions in the coding regions of the GAA gene was done with specific probes for exons 1, 3—10, 12—20 besides to reference probes. The analysis autosomal recessive genetic disorders examples performed using the Coffalyser software. The samples from patients were studied males, mean age SD: standard deviation.

P: Pathogenic Variants. LP: Likely Pathogenic Variants. Out of patients, No novel variants were identified. CAPN3: Calpain 3. ANO5: Anoctamin 5. DYSF: Dysferlin. TCAP: Telethonin. P: Pathogenic. LP: Likely Pathogenic. ANO5: Anoctamin. CAV3: Caveolin 3. Frequency of variants identified. The 72 remaining patients presented heterozygous variants for autosomal recessive diseases and were confirmed as carriers. Genetic muscular diseases diagnosed in the study.

In 12 of them a definitive molecular diagnosis of PD was confirmed, being all compounds heterozygous. We further obtained a detailed medical history of each of the confirmed patients with PD. In autosomal recessive genetic disorders examples patients with PD a low blood enzymatic activity was already known by the primary clinician by the time of the genetic panel referral. Thus, in these 10 patients with PD the panel was requested to dislrders confirm the diagnosis rather than for screening purposes.

In the remaining two patients with PD, the suspected diagnosis was a LGMD and enzymatic studies were not requested before performing the genetic panel. Seven of them had a normal MLPA and in the other two patients the study was not performed. Among the patients with a normal MLPA, the enzymatic activity was low in only two patients. The first patient was a year-old man presenting with myalgia and carrying the variant c.

The second one, was a year-old man presenting with hiperckemia and mild tongue what is dog food mixer neck flexor weakness and carrying the variant c. Both patients had a first degree relative with a genetic and clinical diagnosis of PD, a maternal uncle in the former and the father of the patient in the latter. This paper represents the first genetic multicenter study of LGMD and PD performed in Argentina and evaluated by a centralized single reference laboratory.

Autosomal recessive genetic disorders examples, two additional Brazilian studies identified dysferlin mutations as the most common cause of LGMD 2122 in examplew country. The difference in the LGMD distribution between neighbour countries might be due to historical reason since Argentina was an Spanish colony and had a remarkable immigration from mainly Italy and Spain at the end of the 19th century and the first decades of the 20th century, 23 whereas Examoles had an important Portuguese immigration background.

This frequency is similar to that reported on previous studies. Screening genetic studies searching for PD should carefully exclude patients with known low GAA enzymatic levels in order to inform a more accurate PD frequency Table 5. In the first one, patients with a LGMD phenotype, hyperckemia or an unspecified myopathy were initially studied with enzymatic assays and the results were lately confirmed with a genetic technique.

The reported PD frequency using this autosomal recessive genetic disorders examples was between 1. The inclusion of patients with family history or previous abnormal enzymatic levels could be opened to selection bias. Pompe disease frequency reported in the literature. Rxamples Pompe Disease. Nine patients had an heterozygous pathogenic variant in the GAA gene, among whom two had a low enzymatic essay despite the fact that a second variant in the GAA gene could not be identified through MLPA.

This finding could be due to limitations of the study methodology used to detect intronic or cryptic gene variants. Although this finding did not modify the frequency of patients with a definitive diagnosis of PD in this study, as the molecular diagnostic criteria was not fulfilled by none of these two patients, they both showed mild phenotypes of PD. Patients with similar clinical and molecular findings were reported to respond to enzyme replacement therapy 34 and should prompt further investigations to identify a second variant in the GAA gene that could explain the patients clinical features.

Limitations of this work include its retrospective nature with lack and a non-homogeneous collection of detailed clinical information of the majority of the patients, the use of a bounded genetic panel and the lack of family segregation analysis. Finally, whole exome sequencing, 11 whole genome sequencing and RNA-seq-based transcriptome analysis 35 were not feasible.

We identified a genetic muscular disorder in Molecular tests are useful tools for a prompt diagnosis of muscular genetic disorders, allowing their early recognition, consideration for treatment and genetic counseling. Results of molecular studies need to be integrated with clinical and complementary assessments to reach a final diagnosis. Inclusion criteria for genetic screening evaluations of muscular disorders could critically affect the results, so, information regarding family history, previous abnormal muscle pathology or abnormal enzymatic assays for PD should be carefully excluded since they may lead to frequency inaccuracies.
