PLCH1
Function
The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by calcium-activated phosphatidylinositol-specific phospholipase C enzymes.
Involvement in disease
Holoprosencephaly 14
HPE14
An autosomal recessive form of holoprosencephaly, a structural anomaly of the brain in which the developing forebrain fails to correctly separate into right and left hemispheres. Holoprosencephaly is genetically heterogeneous and associated with several distinct facies and phenotypic variability. In its most severe form (alobar holoprosencephaly), the forebrain consists of a single ventricle, and midbrain structures may be malformed as well. In the most extreme cases, anophthalmia or cyclopia is evident along with a congenital absence of the mature nose. In milder forms (semilobar or lobar holoprosencephaly), rudimentary midline structures are present. The less severe form features facial dysmorphism characterized by ocular hypertelorism, defects of the upper lip and/or nose, and absence of the olfactory nerves or corpus callosum.
None
The disease is caused by variants affecting the gene represented in this entry.
Tissue Specificity
Expressed in brain and to a lower extent in lung. In brain, it is found in cerebrum, cerebellum and spinal cord. In embryo expressed in the notochord, developing spinal cord (in a ventral to dorsal gradient), dorsal root ganglia, cerebellum and dermatomyosome.
