The variant allele was found at a frequency of 0.35 in 151,928 control chromosomes in the GnomAD database, including 9,682 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 0.35 (9682 hom., cov: 31)
• Consequence: DIP2A NM_015151.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.681

Genes affected

DIP2A (HGNC:17217): (disco interacting protein 2 homolog A) The protein encoded by this gene may be involved in axon patterning in the central nervous system. This gene is not highly expressed. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.413 is higher than 0.05.
