Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 31, 2023The c.710C>T (p.T237M) alteration is located in exon 5 (coding exon 5) of the GSG1L gene. This alteration results from a C to T substitution at nucleotide position 710, causing the threonine (T) at amino acid position 237 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
