Revealing the Mystery Behind Down Syndrome: Chromosome Analysis, Physical Display and Student IQ Level at SLB Type C YPAC Medan

Introduction

Extraordinary School (SLB) type C of the Medan Defendant Child Development Foundation (YPAC) is a place for students with various special needs, including students with mental retardation. Mental retardation, or better known as intellectual disability, is a condition characterized by intellectual function below average, measured by an IQ value below 70. Although many causes of mental retardation, one of the most common is chromosomal disorders, especially trisomy 21 or Down syndrome. This research aims to reveal more about Down syndrome in students at SLB YPAC Medan, focusing on chromosome analysis, physical appearance, and student IQ level.

Background of Down Syndrome

Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. This condition is characterized by intellectual disability, delayed speech and language development, and physical characteristics such as short stature, small head size, and small ears. The prevalence of Down syndrome is estimated to be around 1 in 700 births, making it one of the most common genetic disorders. Despite its prevalence, Down syndrome remains a mystery, and there is a need for more research to understand its causes, consequences, and implications for individuals and families affected by it.

Methodology

This study uses a descriptive method with a *cross-sectional *approach, involving 21 students who meet the criteria as a sample of a total of 99 students with mental retardation. The study analyzes three important aspects:

Chromosome Analysis

Through the cytogenetic method, researchers study the composition of chromosomes in 21 students. The results showed 13 students (76.5%) experiencing trisomy 21 nondisjunction, which has an additional 21 chromosome. The rest has different variations of chromosome abnormalities. This finding suggests that trisomy 21 is a common cause of Down syndrome in students at SLB YPAC Medan.

Physical Appearance

Researchers observe the physical characteristics of students directly. The results show that the majority of students (68.4%) have short stature, 57.9% have microcephalus (small heads), and 47.4% have small ears. In addition, several other characteristics such as Simean Crease (transverse hand lines), palm width, gaps between toes, and the size of the soles of the feet are also found in students with Down syndrome. These physical characteristics are common in individuals with Down syndrome and can be used as diagnostic markers.

IQ Level

Student IQ data obtained from school records. Of the 19 students, 10 students (52.6%) were classified as moderate mental retardation with 35-49 IQ scores, while 9 students (47.4%) were classified as mild mental retardation with an IQ value of 50-69. This finding suggests that students with Down syndrome at SLB YPAC Medan have varying levels of intellectual disability, ranging from mild to moderate.

Discussion

The results of this study provide strong evidence of the relationship between Down syndrome and trisomy 21. Excess chromosome 21 causes over-expression of genes in the chromosome, including DSCR1/RCAN1 genes which play an important role in regulating development and organogenesis, including the central nervous system. This finding highlights the importance of chromosome analysis in diagnosing Down syndrome and understanding its causes.

This study provides a clearer picture of Down syndrome and its implications for students at SLB YPAC Medan. This information is very important to increase understanding of the special needs of students with Down syndrome, designing more effective educational programs, and providing appropriate support for them. In addition, this research can also be a foundation for the development of further research on Down syndrome, such as studying the impact of Down syndrome on other aspects besides intellectuals, finding solutions to improve the quality of life of students with Down syndrome, and develop more effective intervention programs.

Conclusion

In conclusion, this study reveals the mystery behind Down syndrome in students at SLB YPAC Medan. The results show that trisomy 21 is a common cause of Down syndrome, and students with Down syndrome have varying levels of intellectual disability. The study also highlights the importance of chromosome analysis in diagnosing Down syndrome and understanding its causes. This research provides a clearer picture of Down syndrome and its implications for students at SLB YPAC Medan, and it can be a foundation for further research on Down syndrome.

Recommendations

Based on the findings of this study, the following recommendations are made:

Chromosome analysis should be conducted regularly to diagnose Down syndrome and understand its causes.
Educational programs should be designed to meet the special needs of students with Down syndrome, including those with varying levels of intellectual disability.
Support services should be provided to students with Down syndrome and their families to improve their quality of life.
Further research should be conducted on Down syndrome, including its impact on other aspects besides intellectuals, to develop more effective intervention programs.

Limitations

This study has several limitations, including:

The sample size is small, and the results may not be generalizable to other populations.
The study only focuses on chromosome analysis, physical appearance, and IQ level, and does not consider other aspects of Down syndrome.
The study does not provide a comprehensive understanding of the causes and consequences of Down syndrome.

Future Research Directions

Future research should focus on:

Studying the impact of Down syndrome on other aspects besides intellectuals, such as social and emotional development.
Finding solutions to improve the quality of life of students with Down syndrome and their families.
Developing more effective intervention programs for students with Down syndrome.

Frequently Asked Questions About Down Syndrome

Down syndrome is a genetic disorder that affects approximately 1 in 700 births worldwide. It is a complex condition that requires a comprehensive understanding of its causes, consequences, and implications for individuals and families affected by it. In this article, we will address some of the most frequently asked questions about Down syndrome.

Q: What is Down syndrome?

A: Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. This condition is characterized by intellectual disability, delayed speech and language development, and physical characteristics such as short stature, small head size, and small ears.

Q: What are the causes of Down syndrome?

A: The primary cause of Down syndrome is trisomy 21, which occurs when there is an extra copy of chromosome 21. This can happen in several ways, including:

Nondisjunction: This occurs when the chromosomes do not separate properly during cell division, resulting in an extra copy of chromosome 21.
Mosaicism: This occurs when there is a mixture of cells with and without an extra copy of chromosome 21.
