Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.1813G>A (p.A605T) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a G to A substitution at nucleotide position 1813, causing the alanine (A) at amino acid position 605 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
