Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.1450G>A (p.V484I) alteration is located in exon 11 (coding exon 10) of the GALNTL6 gene. This alteration results from a G to A substitution at nucleotide position 1450, causing the valine (V) at amino acid position 484 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
