Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 26, 2024The c.1301G>A (p.R434Q) alteration is located in exon 13 (coding exon 13) of the SIDT1 gene. This alteration results from a G to A substitution at nucleotide position 1301, causing the arginine (R) at amino acid position 434 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
