Disability Benefits for Down Syndrome

How SSA Evaluates Down Syndrome Under Listing 10.06

Down syndrome is evaluated under Blue Book listing 10.06 among the congenital disorders that affect multiple body systems. How you qualify depends on the type of Down syndrome you have.

Non-Mosaic Down Syndrome

Non-mosaic Down syndrome — the most common form, where every cell has an extra copy of chromosome 21 (trisomy 21) or an unbalanced translocation — meets listing 10.06 on the diagnosis alone. Because it consistently affects development and multiple body systems, SSA treats it as disabling once the diagnosis is properly documented. You can establish the diagnosis in one of two ways:

• A laboratory report of karyotype (chromosome) analysis showing the trisomy or translocation, signed by a physician; or
• A physician's statement that you have non-mosaic Down syndrome, together with evidence that you have the distinctive features and developmental limitations of the condition.

Non-mosaic Down syndrome is also on SSA's Compassionate Allowances list, which means the claim is flagged for expedited processing and can be approved quickly when the diagnosis is clearly documented.

Mosaic Down Syndrome

Mosaic Down syndrome, where only some cells have the extra chromosome, does not automatically meet listing 10.06. Instead, SSA evaluates it under the listings for the body systems it affects — for example, intellectual disorder under the mental listings (12.05), congenital heart disease under the cardiovascular listings, or other affected systems. Many people with mosaic Down syndrome still qualify based on the combination of their limitations.

Medical Evidence for a Down Syndrome Claim

The evidence SSA needs depends on the form of Down syndrome, but the goal is always to establish the diagnosis and its effects. Helpful records include:

• Karyotype or genetic testing — a laboratory report showing trisomy 21 or a translocation, which is the strongest proof for non-mosaic Down syndrome.
• A physician's statement confirming the diagnosis and describing the characteristic features, if genetic testing is not in the file.
• Developmental and cognitive records — evaluations of intellectual functioning, school records, and assessments of daily living skills.
• Records of associated conditions — congenital heart defects, thyroid disorders, hearing and vision problems, and other health issues common with Down syndrome.

For non-mosaic Down syndrome, a clear diagnosis is usually enough, so getting the karyotype report or a physician's statement into the file quickly is the priority. For mosaic Down syndrome, records that document intellectual limitations, heart disease, and other affected systems become the heart of the claim, because SSA evaluates those body systems individually and in combination.

How Function Is Considered for Down Syndrome

For non-mosaic Down syndrome, a residual functional capacity (RFC) assessment is usually unnecessary, because the condition meets the listing on the diagnosis alone. The focus is simply on documenting the diagnosis so the claim can be approved, often quickly through Compassionate Allowances processing.

For mosaic Down syndrome, function matters more directly. SSA looks at intellectual functioning and adaptive skills — communication, self-care, social interaction, and the ability to learn and complete tasks — under the mental disorders rules, and it considers physical limitations from heart disease, low muscle tone, and other conditions. For adults, this may involve assessing the ability to understand and carry out instructions, maintain concentration and pace, interact appropriately with others, and adapt to changes in a work setting. When these limitations are combined, many people with mosaic Down syndrome are found unable to sustain competitive full-time work. Documentation from doctors, psychologists, teachers, and caregivers all helps paint the full picture.

Tips for a Stronger Down Syndrome Claim

• Submit the genetic report early. For non-mosaic Down syndrome, a karyotype showing trisomy 21 or a physician's statement can approve the claim quickly under Compassionate Allowances.
• State the type clearly. Make sure the application specifies non-mosaic versus mosaic, since the evaluation is very different.
• For mosaic Down syndrome, document every system — intellectual functioning, heart, thyroid, hearing, and vision — because the claim is built on combined limitations.
• Gather functional evidence from doctors, psychologists, teachers, and caregivers describing daily living and learning skills.
• Consider SSI for children and low-income adults, and remember that a claim can be filed as soon as the diagnosis is confirmed.
