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]
TNR Gene-Disease associations (from GenCC):
  • neurodevelopmental disorder, nonprogressive, with spasticity and transient opisthotonus

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.875
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00027 (41/152068) while in subpopulation NFE AF = 0.000515 (35/68004). AF 95% confidence interval is 0.00038. There are 0 homozygotes in GnomAd4. There are 20 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAdExome4 at 3 AR gene
