Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.962G>A (p.R321Q) alteration is located in exon 8 (coding exon 7) of the GALNTL6 gene. This alteration results from a G to A substitution at nucleotide position 962, causing the arginine (R) at amino acid position 321 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
