Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2023The c.844G>A (p.A282T) alteration is located in exon 7 (coding exon 6) of the GALNTL6 gene. This alteration results from a G to A substitution at nucleotide position 844, causing the alanine (A) at amino acid position 282 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
