5 Rare Yet Common Diseases In Newborns

Infrequently occurring ailments found in newborns, often labeled as orphan diseases, pose a significant health hurdle impacting millions globally. These disorders, marked by their rarity within the general populace, encompass genetic, metabolic, or congenital origins.

Genetic disorders stem from abnormalities in DNA and are typically hereditary. Metabolic disorders arise when the body struggles to metabolize specific nutrients and chemicals, whereas congenital anomalies manifest as physical abnormalities present at birth. Pinpointing these conditions proves challenging due to symptom similarities with more prevalent illnesses.

# Down Syndrome

Within this spectrum, Down syndrome stands out as the most prevalent genetic disorder, attributed to an additional copy of Chromosome 21. Its incidence reaches around 1 in every 700 live births in the US, highlighting the urgent necessity for prenatal screening and genetic counseling for prospective parents. Recognizable by distinctive facial features and congenital heart defects, Down syndrome requires a comprehensive approach to care and support.

# Turner Syndrome

Affecting approximately 1 in every 2,000 female births, Turner syndrome results from a missing X chromosome. Often remaining undiagnosed until puberty, symptoms such as delayed puberty and infertility become apparent. Short stature and congenital heart defects also pose additional health concerns, underscoring the pivotal role of genetic counseling in tailored testing and management.

# Fragile X Syndrome

More prevalent in males, Fragile X syndrome occurs in 1 out of every 4,000 to 6,000 live births due to a mutation in the FMR1 gene. This condition leads to intellectual disability, developmental delays, and behavioral challenges. Genetic testing is essential for diagnosing children with developmental delays or behavioral issues, facilitating the identification and management of Fragile X syndrome.

# Tay-Sachs Syndrome

Tay-Sachs syndrome is a degenerative genetic disorder typically evident in infants between 3 and 6 months of age. Characterized by regression in physical development, muscle weakness, seizures, and loss of vision and hearing capabilities, it is particularly prevalent among children of Ashkenazi Jewish descent. Genetic testing is strongly recommended for prospective parents in such populations.

# Phenylketonuria (PKU)

Another inherited genetic disorder, Phenylketonuria leads to the accumulation of phenylalanine in the blood, potentially resulting in intellectual disability and severe health complications without timely intervention. Early detection and treatment through newborn screening are crucial, emphasizing the importance of proactive healthcare measures.
