Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2023The c.2775G>C (p.Q925H) alteration is located in exon 20 (coding exon 20) of the GLG1 gene. This alteration results from a G to C substitution at nucleotide position 2775, causing the glutamine (Q) at amino acid position 925 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
