Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.475G>A (p.E159K) alteration is located in exon 3 (coding exon 3) of the GSG1L gene. This alteration results from a G to A substitution at nucleotide position 475, causing the glutamic acid (E) at amino acid position 159 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
