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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.595C>T (p.R199W) alteration is located in exon 8 (coding exon 6) of the RPH3A gene. This alteration results from a C to T substitution at nucleotide position 595, causing the arginine (R) at amino acid position 199 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
