Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.191G>A (p.R64H) alteration is located in exon 2 (coding exon 2) of the SMYD1 gene. This alteration results from a G to A substitution at nucleotide position 191, causing the arginine (R) at amino acid position 64 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
