Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.380A>T (p.H127L) alteration is located in exon 4 (coding exon 3) of the STXBP6 gene. This alteration results from a A to T substitution at nucleotide position 380, causing the histidine (H) at amino acid position 127 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
