Variant summary

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

The NM_130808.3(CPNE4):​c.-1-1871G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.712 in 151,986 control chromosomes in the GnomAD database, including 38,806 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 0.71 (38806 hom., cov: 31)
• Consequence: CPNE4 NM_130808.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.346

Genes affected

CPNE4 (HGNC:2317): (copine 4) This gene belongs to the highly conserved copine family. It encodes a calcium-dependent, phospholipid-binding protein, which may be involved in membrane trafficking, mitogenesis and development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.794 is higher than 0.05.
