The c.1144C>A (p.R382S) alteration is located in exon 7 (coding exon 7) of the NUDCD1 gene. This alteration results from a C to A substitution at nucleotide position 1144, causing the arginine (R) at amino acid position 382 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
