Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.1870G>A (p.D624N) alteration is located in exon 17 (coding exon 17) of the NDC1 gene. This alteration results from a G to A substitution at nucleotide position 1870, causing the aspartic acid (D) at amino acid position 624 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
