The c.295G>T (p.V99L) alteration is located in exon 4 (coding exon 2) of the NRSN1 gene. This alteration results from a G to T substitution at nucleotide position 295, causing the valine (V) at amino acid position 99 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
