Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2024The c.1883A>G (p.D628G) alteration is located in exon 14 (coding exon 14) of the STRN3 gene. This alteration results from a A to G substitution at nucleotide position 1883, causing the aspartic acid (D) at amino acid position 628 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
