Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 18, 2023The c.1628G>A (p.R543H) alteration is located in exon 10 (coding exon 10) of the RETSAT gene. This alteration results from a G to A substitution at nucleotide position 1628, causing the arginine (R) at amino acid position 543 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
