Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.607A>G (p.S203G) alteration is located in exon 4 (coding exon 4) of the GSG1L gene. This alteration results from a A to G substitution at nucleotide position 607, causing the serine (S) at amino acid position 203 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
