Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.1362C>A (p.F454L) alteration is located in exon 8 (coding exon 8) of the RETSAT gene. This alteration results from a C to A substitution at nucleotide position 1362, causing the phenylalanine (F) at amino acid position 454 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
