Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.823C>T (p.R275W) 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 823, causing the arginine (R) at amino acid position 275 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
