Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.437T>C (p.I146T) alteration is located in exon 6 (coding exon 5) of the RBM18 gene. This alteration results from a T to C substitution at nucleotide position 437, causing the isoleucine (I) at amino acid position 146 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
