Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.1042C>G (p.L348V) alteration is located in exon 7 (coding exon 4) of the NAB1 gene. This alteration results from a C to G substitution at nucleotide position 1042, causing the leucine (L) at amino acid position 348 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
