Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.2497C>T (p.R833C) alteration is located in exon 16 (coding exon 15) of the MED16 gene. This alteration results from a C to T substitution at nucleotide position 2497, causing the arginine (R) at amino acid position 833 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
