Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.1006T>C (p.S336P) alteration is located in exon 9 (coding exon 9) of the KHDRBS2 gene. This alteration results from a T to C substitution at nucleotide position 1006, causing the serine (S) at amino acid position 336 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
