Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.625C>T (p.R209W) alteration is located in exon 2 (coding exon 2) of the GALNT15 gene. This alteration results from a C to T substitution at nucleotide position 625, causing the arginine (R) at amino acid position 209 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
