Sep 17, 2021

The c.274G>T (p.V92L) alteration is located in exon 4 (coding exon 4) of the SNX31 gene. This alteration results from a G to T substitution at nucleotide position 274, causing the valine (V) at amino acid position 92 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
