Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.961A>G (p.I321V) alteration is located in exon 6 (coding exon 6) of the NOL4 gene. This alteration results from a A to G substitution at nucleotide position 961, causing the isoleucine (I) at amino acid position 321 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
