Can there be a birth defect in the hypoglossal nerve, which detoriates the brain in later years? if so, what will it be called?

Hypoglossal Nerve : function can be impacted by prenatal strokes, prenatal infections, some congenital anomalies like Möbius Syndrome or branchial arch cysts, especially infected ones, or post-natal tumor or infection at the base of the brain or neck trauma, any of which can lead to problems with speaking, chewing, or swallowing. Whether it is progressive depends on the cause of the XIIth Cranial Nerve Palsy.
