Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.655A>G (p.T219A) alteration is located in exon 7 (coding exon 6) of the NCAPD2 gene. This alteration results from a A to G substitution at nucleotide position 655, causing the threonine (T) at amino acid position 219 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
