Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 1P and 5B. PP2 BP4 BS2

The NM_001098816.3(TENM4):​c.7912C>T​(p.Arg2638Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000478 in 1,613,988 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2638Q) has been classified as Benign.

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 Likely_benign. Variant got -4 ACMG points.

• 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=0.2646507).
• BS2: High AC in GnomAd4 at 58 AD gene.

Variant summary: TENM4 c.7912C>T (p.Arg2638Trp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00039 in 249072 control chromosomes. To our knowledge, no occurrence of c.7912C>T in individuals affected with Tremor, Hereditary Essential, 5 and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
