Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 1P and 14B. PP2 BP4_Strong BP6_Moderate BS1 BS2

The NM_001098816.3(TENM4):​c.7913G>A​(p.Arg2638Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00154 in 1,614,020 control chromosomes in the GnomAD database, including 39 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2638W) has been classified as Uncertain significance.

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 Benign. Variant got -13 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=0.0059633255).
• BP6: Variant 11-78658455-C-T is Benign according to our data. Variant chr11-78658455-C-T is described in ClinVar as [Benign]. Clinvar id is 787384.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00797 (1214/152326) while in subpopulation AFR AF= 0.0276 (1146/41570). AF 95% confidence interval is 0.0262. There are 20 homozygotes in gnomad4. There are 564 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1214 AD gene.
