Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.3238G>A (p.A1080T) alteration is located in exon 24 (coding exon 24) of the GLG1 gene. This alteration results from a G to A substitution at nucleotide position 3238, causing the alanine (A) at amino acid position 1080 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
