Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.74G>T (p.R25L) alteration is located in exon 1 (coding exon 1) of the KHDRBS3 gene. This alteration results from a G to T substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
