The c.983C>T (p.S328F) alteration is located in exon 6 (coding exon 6) of the NUDCD1 gene. This alteration results from a C to T substitution at nucleotide position 983, causing the serine (S) at amino acid position 328 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
