The c.985C>A (p.L329M) alteration is located in exon 9 (coding exon 8) of the NDEL1 gene. This alteration results from a C to A substitution at nucleotide position 985, causing the leucine (L) at amino acid position 329 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
