Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.353C>T (p.P118L) alteration is located in exon 3 (coding exon 3) of the SPERT gene. This alteration results from a C to T substitution at nucleotide position 353, causing the proline (P) at amino acid position 118 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
