Is Erb's Palsy hereditary?

Erb's Palsy is not a hereditary or genetic condition, but rather a mechanical injury to the brachial plexus nerves occurring during childbirth. Because it is caused by physical trauma during delivery, it cannot be passed from parent to child, and there is no associated inheritance pattern or genetic risk for future pregnancies.

Is Erb's Palsy a genetic condition?

As a clinical geneticist, I want to reassure families that Erb's Palsy is not genetic. It is classified as a birth injury resulting from damage to the upper trunk of the brachial plexus, usually during a difficult delivery. Unlike hereditary syndromes caused by mutations in DNA, Erb's Palsy does not involve genes, chromosomes, or inherited traits.

Are there risk factors for Erb's Palsy in future pregnancies?

Because Erb's Palsy is not hereditary, there is no risk of passing the condition to offspring. The occurrence of Erb's Palsy is multifactorial and linked to obstetric factors rather than familial genetics. Common mechanical risk factors that may lead to Erb's Palsy include:

• Large birth weight (macrosomia)


• Shoulder dystocia during the birthing process


• Prolonged second stage of labor


• Maternal gestational diabetes


• Assisted delivery techniques (e.g., use of forceps or vacuum extraction)

Is genetic testing or counseling needed?

Genetic testing is not indicated for Erb's Palsy because the condition is not caused by gene mutations. Similarly, prenatal genetic diagnosis is not applicable. Genetic counseling is generally not required for families affected by Erb's Palsy, as the recurrence risk is not based on genetic inheritance. If you have concerns about the physical nature of the injury or the recovery prognosis for your child, a pediatric neurologist or a specialized orthopedic surgeon is the appropriate professional to consult.

Next steps

• Consult with a pediatric neurologist or physical therapist to monitor nerve recovery.


• Speak with your obstetrician about delivery planning for future pregnancies to address potential mechanical risks.


• Connect with the Erb's Palsy community at DiseaseMaps.org to share experiences with others who understand the recovery journey.
