Trait

Osteopathia striata

A lamellar pattern visible on radiographs and mainly localized at the metaphyses of the long tubular bones. Pathologic-anatomical studies revealed that these benign signs on x-rays are the result of a juvenile metaphyseal bone necrosis. Calcifications in the necrotic marrow lead to this lamellar or lattice-like appearance.

5 genes linked to Osteopathia striata

Changes in these genes cause rare conditions in which Osteopathia striata 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
RAB3GAP2RAB3 GTPase activating non-catalytic protein subunit 2	Often (30–79%)	In 1 condition
PORCNporcupine O-acyltransferase	Sometimes (5–29%)	In 2 conditions
TONSLtonsoku like, DNA repair protein	Sometimes (5–29%)	In 1 condition
WDR26WD repeat domain 26	Sometimes (5–29%)	In 1 condition
AMER1APC membrane recruitment protein 1	Not recorded	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.
