Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.829A>C (p.I277L) alteration is located in exon 8 (coding exon 8) of the SUN3 gene. This alteration results from a A to C substitution at nucleotide position 829, causing the isoleucine (I) at amino acid position 277 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
