The c.992G>T (p.R331L) alteration is located in exon 8 (coding exon 7) of the TSNARE1 gene. This alteration results from a G to T substitution at nucleotide position 992, causing the arginine (R) at amino acid position 331 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
