I know very little about PCOS except that, like all autoimmune diseases, it has a causal link to gluten. (Google is your friend.) Your son's autism is solid evidence of a familial genetic connection to gluten sensitivity. That's even reinforced by the fact that it's a maternal connection. That connects maternally-inherited mitochondrial DNA.
Like you, many lo-carb savvy people succeed at relieving autoimmune symptoms by cutting out starches. So they blame "carbohydrates". The problem is really a combination of complex sugars (fructose and lactose) and the gluten in glutenous grains (wheat, rye, barley and oats).
You and your son should cut out both for three or four months. See what happens. Try eliminating raw milk from your son's diet for a few weeks too. Milk casein has been strongly linked to autism. Casein and gluten are strong opioids to many people.

I'm convinced a sugar-free gluten-free diet represents the cure for type 2 diabetes, and for all maladies of the metabolic syndrome. So that's another strong link tying your PCOS to gluten ingestion.
Here's my model. The pancreas has nerves which monitor blood endorphin levels in order to regulate the release of insulin. Gluten is the glycoprotein in wheat, rye, barley and oats. Gluten is an opioid, a mimicker of endorphin. It plugs into pancreatic nerve cells, and fools them into thinking the blood is full of endorphin.
The pancreas responds with a constant oversupply of insulin. The added insulin:
* stuffs cells with fat and prevents them from releasing fat
* depletes the pancreas's ability to produce insulin
* traps ingested sugar in the bloodstream
* makes cells resistant to the effects of insulin
Exercise, stop ingesting sweets, stop ingesting gluten, cut back on other starches and glycoproteins. Fill in with cuts of meat.
I'm convinced this regimen is the cure for type 2 diabetes.
Somebody else posted this link earlier. I can cite other, more casual connections:
Effect of gluten exorphins A5 and B5 on the postprandial plasma insulin level in conscious rats
---------------------------------------------------------------------------------------------------------------
The effect of exogenous opioid peptides, gluten exorphins A5 and B5, which were isolated from the enzymatic digest of wheat gluten, on the postprandial insulin level were examined in rats. The oral administration of gluten exorphin A5 at a dose of 30 mg/kg w. potentiated the postprandial plasma insulin level and the effect was reversed by naloxone. The administration of gluten exorphin B5 showed a similar effect at a higher dose (300 mg/kg w). Furthermore, intravenous administration of gluten exorphin A5 at a dose of 30 mg/kg w. also stimulated the postprandial insulin release. The fact that orally and intravenously administered gluten exorphin A5 stimulates insulin release suggests that it modulates pancreatic endocrine function by the action after the absorption rather than within the the gastrointestinal tract.
