The c.1999C>T (p.P667S) alteration is located in exon 18 (coding exon 17) of the ALS2CL gene. This alteration results from a C to T substitution at nucleotide position 1999, causing the proline (P) at amino acid position 667 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
