Genes affected

PDZD8 (HGNC:26974): (PDZ domain containing 8) Predicted to enable lipid binding activity and metal ion binding activity. Involved in several processes, including mitochondrial calcium ion homeostasis; mitochondrion-endoplasmic reticulum membrane tethering; and regulation of cell morphogenesis. Located in endoplasmic reticulum membrane and mitochondria-associated endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

SLC18A2 (HGNC:10935): (solute carrier family 18 member A2) This gene encodes an transmembrane protein that functions as an ATP-dependent transporter of monoamines, such as dopamine, norepinephrine, serotonin, and histamine. This protein transports amine neurotransmitters into synaptic vesicles. Polymorphisms in this gene may be associated with schizophrenia, bipolar disorder, and other neurological/psychiatric ailments.
