Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.1067T>A (p.M356K) alteration is located in exon 3 (coding exon 3) of the SPTY2D1 gene. This alteration results from a T to A substitution at nucleotide position 1067, causing the methionine (M) at amino acid position 356 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
