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: not found (cov: 31)
• Consequence: FSTL4 NM_015082.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.432

Genes affected

FSTL4 (HGNC:21389): (follistatin like 4) Predicted to enable brain-derived neurotrophic factor binding activity and calcium ion binding activity. Predicted to be involved in cell differentiation. Predicted to act upstream of or within negative regulation of brain-derived neurotrophic factor receptor signaling pathway; negative regulation of collateral sprouting; and negative regulation of dendritic spine development. Predicted to be located in extracellular region and secretory granule. [provided by Alliance of Genome Resources, Apr 2022]
