Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.514G>T (p.A172S) alteration is located in exon 5 (coding exon 4) of the STXBP6 gene. This alteration results from a G to T substitution at nucleotide position 514, causing the alanine (A) at amino acid position 172 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
