Breast cancer can sometimes run in families. Certain inherited genetic changes can increase a person’s risk of developing breast and other cancers. BRCA1 and BRCA2 are two important genes linked to hereditary breast and ovarian cancer. These genes help repair damaged DNA, and harmful variants can increase cancer susceptibility. What Is BRCA1 and BRCA2 Genetic […]

What Is Spinal Muscular Atrophy? Spinal Muscular Atrophy (SMA) is an inherited neuromuscular disorder that causes progressive muscle weakness. It occurs when motor neurons, which control voluntary muscle movement, are damaged or lost. SMA can affect babies, children, teenagers, and adults. The age at which symptoms begin and the severity of weakness can vary considerably […]

What Is a Single Profile DNA Test? A Single Profile DNA Test creates a genetic profile from one individual’s biological sample. It typically examines specific DNA regions called short tandem repeats (STRs). The resulting profile can be used as a reference for identification or comparison with another DNA sample when appropriate. How Does a Single Profile DNA Test […]

 What Is an Autism Gene Panel? Explain genetic heterogeneity in autism and why a panel may examine multiple genes associated with neurodevelopmental condition. Autism diagnosis is primarily based on developmental history and behavioral assessment; genetic testing may help investigate an underlying genetic cause or associated condition.   Why Might a Child With Autism Need Genetic Testing? […]

Sudden cardiac death in a young person can appear completely unexpected. In some families, however, there may be an inherited electrical disorder quietly increasing the risk of dangerous heart rhythms. One such condition is catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare inherited arrhythmia that can cause fainting, ventricular tachycardia and, in severe cases, cardiac arrest or […]
