Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.332T>C (p.M111T) alteration is located in exon 3 (coding exon 3) of the SMYD1 gene. This alteration results from a T to C substitution at nucleotide position 332, causing the methionine (M) at amino acid position 111 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
