Why is my mandible shape so fucked?

[NoReedemingFeature]

Like my jaw cuts off at the ends and it doesn't have a normal angle from beneath. My ramus is so inwardly slanted it's definitely not normal. It's also less on my left side than it is on my right.
What's the cause? Nutrient deficiency? Metal poisoning? I'm sure this is environmental as none of my family has a mandible that subhuman

Inwardly slanted ramus = short mandible bone
