The variant allele was found at a frequency of 0.355 in 151,212 control chromosomes in the GnomAD database, including 9,921 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 (9921 hom., cov: 30)
• Consequence: NEGR1 NM_173808.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0660

Genes affected

NEGR1 (HGNC:17302): (neuronal growth regulator 1) Predicted to act upstream of or within several processes, including feeding behavior; locomotory behavior; and positive regulation of neuron projection development. Predicted to be located in extracellular region and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.553 is higher than 0.05.
