Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 15, 2024The c.560G>A (p.R187H) alteration is located in exon 5 (coding exon 5) of the MREG gene. This alteration results from a G to A substitution at nucleotide position 560, causing the arginine (R) at amino acid position 187 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
