Genes affected
MREG (HGNC:25478): (melanoregulin) Predicted to enable phosphatidylinositol binding activity. Predicted to be involved in melanocyte differentiation; melanosome transport; and phagosome maturation. Predicted to act upstream of or within developmental pigmentation. Predicted to be located in late endosome membrane and melanosome membrane. Predicted to be intrinsic component of organelle membrane. Predicted to be part of protein-containing complex. Predicted to be active in melanosome. [provided by Alliance of Genome Resources, Apr 2022]
PECR (HGNC:18281): (peroxisomal trans-2-enoyl-CoA reductase) Enables signaling receptor binding activity and trans-2-enoyl-CoA reductase (NADPH) activity. Involved in phytol metabolic process. Located in peroxisome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2024The c.209T>C (p.L70P) alteration is located in exon 2 (coding exon 2) of the MREG gene. This alteration results from a T to C substitution at nucleotide position 209, causing the leucine (L) at amino acid position 70 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
