Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.812G>A (p.C271Y) alteration is located in exon 7 (coding exon 7) of the SIDT1 gene. This alteration results from a G to A substitution at nucleotide position 812, causing the cysteine (C) at amino acid position 271 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
