Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.2468C>T (p.S823L) alteration is located in exon 19 (coding exon 18) of the NCAPD2 gene. This alteration results from a C to T substitution at nucleotide position 2468, causing the serine (S) at amino acid position 823 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
