Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.232A>G (p.I78V) alteration is located in exon 3 (coding exon 2) of the CTDSPL2 gene. This alteration results from a A to G substitution at nucleotide position 232, causing the isoleucine (I) at amino acid position 78 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
