Sometimes the most frustrating cases are the ones where all the tests come back “normal.” The following case is courtesy of one of our leading genetic practitioners where she explains that genetics can reveal sleep disorders that don’t show up on any conventional testing.
Patient Presentation:
38-year-old female with severe insomnia for 2 years. She could fall asleep initially but would wake at 2-3 AM with racing thoughts and be unable to return to sleep. She’d wake feeling exhausted, experience afternoon crashes, and rely on caffeine to function. Two sleep studies showed normal sleep architecture with no apnea or movement disorders.
“The sleep specialist says there’s nothing wrong with me,” she said, dark circles under her eyes. “But I haven’t had a good night’s sleep in two years. I’m starting to feel like I’m losing my mind.”
The Clinical Dead End:
Her sleep workup was textbook normal:
- Sleep study showed normal REM and deep sleep phases
- No sleep apnea, restless legs, or periodic limb movements
- Cortisol rhythm testing showed normal patterns
- Melatonin levels were appropriate
- Thyroid function optimal
- No obvious anxiety or depression
Every sleep hygiene recommendation had been tried without success.
Genomic Analysis Revealed:
- COMT variants leading to impaired dopamine clearance
- MAOA- variant affecting reduced serotonin and norepinephrine breakdown
- CYP1A2 slow metabolizer related to poor caffeine clearance
- GABA receptor variants affecting reduced GABA sensitivity
- Melatonin receptor polymorphisms which affect decreased melatonin effectiveness
The Hidden Sleep Saboteur:
Her genetics created a perfect storm for middle-of-the-night awakening. The COMT variant meant dopamine, adrenaline and noradrenaline accumulated in her brain throughout the day. By 2-3 AM, when cortisol naturally starts to raise again, the excess dopamine + cortisol was reducing melatonin and was causing hypervigilance and racing thoughts.
Additionally, her CYP1A2 slow variant meant even morning caffeine was still active 12+ hours later, and her GABA receptor variants made her resistant to natural calming mechanisms.
A targeted protocol led to Sleep Transformation:
- Week 2: “I’m sleeping through the night for the first time in months”
- Week 4: Consistent 7-8 hours of uninterrupted sleep
- Week 8: Morning energy returned, no afternoon crashes
- 6-month follow-up: Sustained sleep quality, no longer needs sleep aids
If you are experiencing sleep issues, please consult a qualified and genetically trained naturopath for assistance. Sometimes doing a DNA test is the only way to identify the reasons why things just aren’t working.
