Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.1700A>G (p.D567G) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a A to G substitution at nucleotide position 1700, causing the aspartic acid (D) at amino acid position 567 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
