Genes affected

TENM4 (HGNC:29945): (teneurin transmembrane protein 4) The protein encoded by this gene plays a role in establishing proper neuronal connectivity during development. Defects in this gene have been associated with hereditary essential tremor-5. [provided by RefSeq, Oct 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TENM4. . Gene score misZ 2.7323 (greater than the threshold 3.09). Trascript score misZ 3.5261 (greater than threshold 3.09). GenCC has associacion of gene with tremor, hereditary essential, 5.
• BP4: Computational evidence support a benign effect (MetaRNN=0.11904907).

The c.7928A>G (p.N2643S) alteration is located in exon 34 (coding exon 30) of the TENM4 gene. This alteration results from a A to G substitution at nucleotide position 7928, causing the asparagine (N) at amino acid position 2643 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
