I wonder if the disease I invented is realistic or a total fiction.
There is a real life genetic disease called congenital central hypoventilation syndrome (or Ondine's curse, if you want). People afflicted have a voluntary control of respiration (breathing).
In my story, there is a human that has a genetic disease called congenital central thermoregulation syndrome. That said human must voluntarily control its thermoregulation (this is less radical than The Human Torch from Disney/Marvel's The Fantastic Four, because its body does not turn into fire). Technically, that makes this human mesothermic (lukewarm-blooded) (like a tuna, a honey bee, a great white shark, and a platypus). The timescale is for each five minutes. The temperatures extremes are 18 to 42 Celsius degrees. There is a conscious signaling to brown adipose tissue.
If this genetic disease exists, what is its mode of inheritance? Autosomal dominant (like type 1 von Willebrand disease), autosomal recessive (like cystic fibrosis), X-linked dominant (like X-linked pituitary gigantism), X-linked recessive (like Hunter syndrome), incomplete dominance (like myostatin-associated muscular hypertrophy), or mitochondrial (like Leigh syndrome)?
If this is autosomal, what chromosome is linked? Chromosome 1 (like Hutchinson-Guilford progeria), chromosome 2 (like Ehlers-Danlos syndrome), chromosome 3 (like retinitis pigmentosa), chromosome 4 (like achondroplasia), chromosome 5 (like Sotos syndrome), chromosome 6 (like hemochromatosis), chromosome 7 (like tritanopia), chromosome 8 (like Werner syndrome), chromosome 9 (like cartilage-hair hypoplasia), chromosome 10 (like type 2 multiple endocrine hyperplasia), chromosome 11 (like sickle-cell anaemia), chromosome 12 (like phenylketonuria), chromosome 13 (like Wilson disease), chromosome 14 (like Krabbe disease), chromosome 15 (like Marfan syndrome), chromosome 16 (like Morquio syndrome), chromosome 17 (like type 1 neurofibromatosis), chromosome 18 (like type-C Niemann-Pick disease), chromosome 19 (like Donohue syndrome), chromosome 20 (like adenosine deaminase deficiency), chromosome 21 (like autoimmune polyendrocrinopathy-candidiasis-ectodermal-dystrophy), or chromosome 22 (like type 2 neurofibromatosis)?
I know I made an extremely long enumeration because the vast majority of the human genome is nuclear and autosomal, sorry.
