Genes affected

TNR (HGNC:11953): (tenascin R) This gene encodes a member of the tenascin family of extracellular matrix glycoproteins. The encoded protein is restricted to the central nervous system. The protein may play a role in neurite outgrowth, neural cell adhesion and modulation of sodium channel function. It is a constituent of perineuronal nets. [provided by RefSeq, Aug 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.03972003).

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000046 (7/152272) while in subpopulation SAS AF= 0.000622 (3/4826). AF 95% confidence interval is 0.000169. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 7 AD gene.

The c.3610G>A (p.V1204M) alteration is located in exon 20 (coding exon 18) of the TNR gene. This alteration results from a G to A substitution at nucleotide position 3610, causing the valine (V) at amino acid position 1204 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
