Genes affected

RPH3A (HGNC:17056): (rabphilin 3A) The protein encoded by this gene is thought to be an effector for RAB3A, which is a small G protein that acts in the late stages of neurotransmitter exocytosis. The encoded protein may be involved in neurotransmitter release and synaptic vesicle traffic. [provided by RefSeq, Dec 2016]

Aug 02, 2023

The c.348G>T (p.E116D) alteration is located in exon 6 (coding exon 4) of the RPH3A gene. This alteration results from a G to T substitution at nucleotide position 348, causing the glutamic acid (E) at amino acid position 116 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
