The variant allele was found at a frequency of 0.32 in 151,972 control chromosomes in the GnomAD database, including 8,092 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.32 (8092 hom., cov: 32)
• Consequence: RPH3A NM_001347952.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.196

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.402 is higher than 0.05.
