GeneID: 19


Common Name: FRMPD4 Type: Gene
Chromosome: X (NC_000023.11) Locus: NG_016419.1 (FRMPD4)
HUGO Symbol: FRMPD4 Full Name: FERM and PDZ domain containing 4
Exons: 17 Introns: 16

FRMPD4 is a FERM and PDZ domain-containing protein and is highly expressed in parts of the brain. Through its interaction with other proteins (such as PSD-95), it functions as a positive regulator of dendritic spine morphogenesis and density, and is required for the maintenance of excitatory synaptic transmission. Variation in FRMPD4 gene associated with F-cell numbers and HbF levels in male patients with sickle cell disease (SCD), but not in female patients. FRMPD4 is a candidate X-linked locus that could account for a significant fraction of the variation in F-cell and HbF levels in SCD.

Synonyms: PDZD10 , PDZK10
