Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 30, 2024The c.577G>A (p.E193K) alteration is located in exon 6 (coding exon 5) of the NCAPD2 gene. This alteration results from a G to A substitution at nucleotide position 577, causing the glutamic acid (E) at amino acid position 193 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
