Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.2223G>T (p.E741D) alteration is located in exon 18 (coding exon 17) of the NCAPD2 gene. This alteration results from a G to T substitution at nucleotide position 2223, causing the glutamic acid (E) at amino acid position 741 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
