Genes affected

NTF4 (HGNC:8024): (neurotrophin 4) This gene is a member of a family of neurotrophic factors, neurotrophins, that control survival and differentiation of mammalian neurons. The expression of this gene is ubiquitous and less influenced by environmental signals. While knock-outs of other neurotrophins including nerve growth factor, brain-derived neurotrophic factor, and neurotrophin 3 prove lethal during early postnatal development, NTF5-deficient mice only show minor cellular deficits and develop normally to adulthood.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BP6: Variant 19-49062161-G-A is Benign according to our data. Variant chr19-49062161-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1317038.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0103 (1568/152292) while in subpopulation NFE AF= 0.0166 (1131/68026). AF 95% confidence interval is 0.0158. There are 9 homozygotes in gnomad4. There are 758 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1568 AD gene.
