Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.973C>T (p.L325F) alteration is located in exon 9 (coding exon 9) of the SIDT1 gene. This alteration results from a C to T substitution at nucleotide position 973, causing the leucine (L) at amino acid position 325 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
