Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2022The c.548A>T (p.N183I) alteration is located in exon 5 (coding exon 5) of the NUPL2 gene. This alteration results from a A to T substitution at nucleotide position 548, causing the asparagine (N) at amino acid position 183 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
