Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.961T>C (p.C321R) alteration is located in exon 6 (coding exon 3) of the NAB1 gene. This alteration results from a T to C substitution at nucleotide position 961, causing the cysteine (C) at amino acid position 321 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
