Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.1333T>C (p.Y445H) alteration is located in exon 10 (coding exon 9) of the GALNTL6 gene. This alteration results from a T to C substitution at nucleotide position 1333, causing the tyrosine (Y) at amino acid position 445 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
