When it defoliated last fall I noted these oddly curled growths. There were about a dozen of them on a 12 foot plant, not a large percentage of shoot tips.It's not genetic but I don't know what caused them. Sometimes insects inadvertently inject chemicals that function as plant growth regulators. Maybe even verdently sic, though I can't imagine the advantage to an insect in this particular case. So maybe it was an insect, or maybe a fungus, or possibly even some free range chemical floating in the air. Anyway, the plant seems unaffected by them with new shoots sprouting as usual.
