Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2023The c.1172C>T (p.P391L) alteration is located in exon 12 (coding exon 12) of the SIDT1 gene. This alteration results from a C to T substitution at nucleotide position 1172, causing the proline (P) at amino acid position 391 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
