Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_001143854.2(RPH3A):​c.72-1246C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.313 in 152,034 control chromosomes in the GnomAD database, including 7,752 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 0.31 (7752 hom., cov: 33)
• Consequence: RPH3A NM_001143854.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.966

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=-0.75).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.348 is higher than 0.05.
