Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 18, 2023The c.3135G>T (p.L1045F) alteration is located in exon 23 (coding exon 23) of the GLG1 gene. This alteration results from a G to T substitution at nucleotide position 3135, causing the leucine (L) at amino acid position 1045 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
