Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.449C>T (p.T150I) alteration is located in exon 1 (coding exon 1) of the GALNT15 gene. This alteration results from a C to T substitution at nucleotide position 449, causing the threonine (T) at amino acid position 150 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
