ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009893984).

BS2

High Homozygotes in GnomAdExome4 at 2 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.949A>C (p.S317R) alteration is located in exon 8 (coding exon 8) of the TGM4 gene. This alteration results from a A to C substitution at nucleotide position 949, causing the serine (S) at amino acid position 317 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
