Genes affected

PLPPR1 (HGNC:25993): (phospholipid phosphatase related 1) This gene encodes a member of the plasticity-related gene (PRG) family. Members of the PRG family mediate lipid phosphate phosphatase activity in neurons and are known to be involved in neuronal plasticity. The protein encoded by this gene does not perform its function through enzymatic phospholipid degradation. This gene is strongly expressed in brain. It shows dynamic expression regulation during brain development and neuronal excitation. Alternatively spliced transcript variants encoding the same protein have been observed.

The c.559G>A (p.E187K) alteration is located in exon 5 (coding exon 4) of the PLPPR1 gene. This alteration results from a G to A substitution at nucleotide position 559, causing the glutamic acid (E) at amino acid position 187 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
