Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.590G>A (p.R197Q) alteration is located in exon 6 (coding exon 5) of the GALNTL6 gene. This alteration results from a G to A substitution at nucleotide position 590, causing the arginine (R) at amino acid position 197 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
