Genes affected

PLA2G4B (HGNC:9036): (phospholipase A2 group IVB) This gene encodes a member of the cytosolic phospholipase A2 protein family. Phospholipase A2 enzymes hydrolyze the sn-2 bond of phospholipids, releasing lysophospholipids and fatty acids. This enzyme may be associated with mitochondria and early endosomes. Most tissues also express read-through transcripts from the upstream gene into this gene, some of which may encode fusion proteins combining the N-terminus of the upstream gene including its JmjC domain with the almost complete coding region of this gene, including the C2 and cytoplasmic phospholipase A2 domains.

Feb 16, 2023

The c.779C>T (p.T260I) alteration is located in exon 8 (coding exon 8) of the JMJD7-PLA2G4B gene. This alteration results from a C to T substitution at nucleotide position 779, causing the threonine (T) at amino acid position 260 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
