The c.91G>A (p.V31I) alteration is located in exon 1 (coding exon 1) of the TMEM196 gene. This alteration results from a G to A substitution at nucleotide position 91, causing the valine (V) at amino acid position 31 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
