Collection Method: clinical testing

The c.4379C>T (p.P1460L) alteration is located in exon 7 (coding exon 7) of the NHSL1 gene. This alteration results from a C to T substitution at nucleotide position 4379, causing the proline (P) at amino acid position 1460 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
