The variant allele was found at a frequency of 0.892 in 152,184 control chromosomes in the GnomAD database, including 60,790 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 0.89 (60790 hom., cov: 31)
• Consequence: FNDC3B NM_022763.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.0130

Genes affected

FNDC3B (HGNC:24670): (fibronectin type III domain containing 3B) Enables RNA binding activity. Predicted to act upstream of or within several processes, including negative regulation of osteoblast differentiation; substrate adhesion-dependent cell spreading; and type II pneumocyte differentiation. Predicted to be located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.
