The c.176A>T (p.D59V) alteration is located in exon 4 (coding exon 3) of the TMEM116 gene. This alteration results from a A to T substitution at nucleotide position 176, causing the aspartic acid (D) at amino acid position 59 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
