Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.377G>A (p.R126H) alteration is located in exon 5 (coding exon 4) of the NCAPD2 gene. This alteration results from a G to A substitution at nucleotide position 377, causing the arginine (R) at amino acid position 126 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
