Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2021The c.734G>A (p.R245K) alteration is located in exon 6 (coding exon 6) of the KHDRBS3 gene. This alteration results from a G to A substitution at nucleotide position 734, causing the arginine (R) at amino acid position 245 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
