Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2024The c.647G>A (p.G216E) alteration is located in exon 7 (coding exon 7) of the SUN3 gene. This alteration results from a G to A substitution at nucleotide position 647, causing the glycine (G) at amino acid position 216 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
