Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2022The c.362C>T (p.S121L) alteration is located in exon 4 (coding exon 4) of the CTDSPL gene. This alteration results from a C to T substitution at nucleotide position 362, causing the serine (S) at amino acid position 121 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
