Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.1699G>T (p.D567Y) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a G to T substitution at nucleotide position 1699, causing the aspartic acid (D) at amino acid position 567 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
