Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2023The c.2119C>T (p.R707W) alteration is located in exon 9 (coding exon 8) of the SMYD4 gene. This alteration results from a C to T substitution at nucleotide position 2119, causing the arginine (R) at amino acid position 707 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
