non-specific some genes? why not "some non-specific genes"?

"non-specific some genes" sounds awkward to me.
What do you think?
Has "some non-specific genes" the same meaning?

Context:

A deeper understanding of the underlying biology is essential to
improve diagnoses and therapies. New techniques - genome-wide
association studies, imaging and the optical manipulation of neural

circuits - are ushering in an era in which the neural circuitry underlying cognitive dysfunctions, for example, will be delineated. Tantalizingly, work in genetics is indicating how non-specific some genes are for schizophrenia, having associations in common with bipolar disorder and with autism. This
suggests that the earlier stages of psychiatric disorders are multi valent,
reinforcing the hope that early detection, coupled with a clearer under-
standing of the environmental factors, may allow prevention.
