Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.2345C>T (p.T782M) alteration is located in exon 17 (coding exon 17) of the GLG1 gene. This alteration results from a C to T substitution at nucleotide position 2345, causing the threonine (T) at amino acid position 782 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
