Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.514C>T (p.R172C) alteration is located in exon 5 (coding exon 5) of the MREG gene. This alteration results from a C to T substitution at nucleotide position 514, causing the arginine (R) at amino acid position 172 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
