Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.647G>A (p.R216H) 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 647, causing the arginine (R) at amino acid position 216 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
