Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.517A>G (p.N173D) alteration is located in exon 3 (coding exon 3) of the GSG1L gene. This alteration results from a A to G substitution at nucleotide position 517, causing the asparagine (N) at amino acid position 173 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
