Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 19, 2022The c.916C>T (p.R306C) alteration is located in exon 9 (coding exon 9) of the NCBP3 gene. This alteration results from a C to T substitution at nucleotide position 916, causing the arginine (R) at amino acid position 306 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
