I have noticed multiple cases where patients had similar body characteristics :
decreased ability to gain weight (slim)
they are capable of sleep only 6 hours or less with normal functioning (although they prefer long sleep)
increased susceptibility to ligaments and connective tissue damages
CVS morbidities: example angina
I think its a good opportunity to ask here what could this mutation be and how would someone search for such characteristics in gene mutation databases.
I searched a lot using ordinary way and found a possible match ( ADRB1 receptor mutation) it causes the affected person ability to sleep less hour and CVS symptoms but i can't confirm if that's the case with the first and third characteristics.
