Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.305C>T (p.P102L) alteration is located in exon 3 (coding exon 3) of the SMYD2 gene. This alteration results from a C to T substitution at nucleotide position 305, causing the proline (P) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
