Homozygous truncating mutation of the KBP gene, encoding a KIF1B-binding protein, in a familial case of fetal polymicrogyria

Neurogenetics. 2013 Nov;14(3-4):215-24. doi: 10.1007/s10048-013-0373-x. Epub 2013 Sep 27.


Polymicrogyria (PMG) is a clinically heterogeneous malformation of cortical development, characterized by a loss of the normal gyral pattern that is replaced by many small and infolded gyri separated by shallow sulci that are partly fused in their depths. Causes of PMG are heterogeneous and include acquired and genetic causes. There are more than 100 syndromes possibly associated with PMG but mutations in specific genes such as SRPX2, GPR56, TUBB2B, TUBB3, NHEJ1, TUBA1A, TUBA8, and WDR62 have been reported only in a minority of patients.
