Is the son of a deceased brother entitled to inherit from his uncle who passed away without children, leaving behind a wife and three sisters?

For the two sisters, two-thirds, as Allah Almighty says: "But if there are two [sisters], they shall have two-thirds of what he leaves." For the wife, one-fourth, as Allah Almighty says: "And for them [wives] will be one-fourth of what you leave if you have no child." For the paternal cousin, what remains, as the Prophet, peace and blessings be upon him, said: "Give the prescribed shares to those who are entitled to them, and whatever remains is for the closest male heir." The issue is out of twelve: eight for the sisters, three for the wife, and one share remains for the paternal cousin.
