9 genes linked to Abnormal parietal bone morphology

Changes in these genes cause rare conditions in which Abnormal parietal bone morphology is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.

Gene	How often it is seen	Conditions
FIG4FIG4 phosphoinositide 5-phosphatase	Often (30–79%)	In 1 condition
VAC14VAC14 component of PIKFYVE complex	Often (30–79%)	In 1 condition
PGAP2post-GPI attachment to proteins 2	Sometimes (5–29%)	In 1 condition
PGAP3post-GPI attachment to proteins phospholipase 3	Sometimes (5–29%)	In 1 condition
PIGLphosphatidylinositol glycan anchor biosynthesis class L	Sometimes (5–29%)	In 1 condition
PIGOphosphatidylinositol glycan anchor biosynthesis class O	Sometimes (5–29%)	In 1 condition
PIGVphosphatidylinositol glycan anchor biosynthesis class V	Sometimes (5–29%)	In 1 condition
PIGWphosphatidylinositol glycan anchor biosynthesis class W	Sometimes (5–29%)	In 1 condition
PIGYphosphatidylinositol glycan anchor biosynthesis class Y	Sometimes (5–29%)	In 1 condition

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
