Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.1633C>T (p.H545Y) alteration is located in exon 10 (coding exon 10) of the RETSAT gene. This alteration results from a C to T substitution at nucleotide position 1633, causing the histidine (H) at amino acid position 545 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
