Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.2245C>T (p.R749C) alteration is located in exon 13 (coding exon 12) of the MED16 gene. This alteration results from a C to T substitution at nucleotide position 2245, causing the arginine (R) at amino acid position 749 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
