The c.1661A>T (p.D554V) alteration is located in exon 10 (coding exon 10) of the NUDCD1 gene. This alteration results from a A to T substitution at nucleotide position 1661, causing the aspartic acid (D) at amino acid position 554 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
