The c.997C>T (p.R333C) alteration is located in exon 9 (coding exon 8) of the NDEL1 gene. This alteration results from a C to T substitution at nucleotide position 997, causing the arginine (R) at amino acid position 333 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
