The c.709C>T (p.L237F) alteration is located in exon 6 (coding exon 6) of the NIPSNAP3A gene. This alteration results from a C to T substitution at nucleotide position 709, causing the leucine (L) at amino acid position 237 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
