Genes affected
MGRN1 (HGNC:20254): (mahogunin ring finger 1) Enables ubiquitin-protein transferase activity. Involved in endosome to lysosome transport; negative regulation of signal transduction; and protein monoubiquitination. Located in several cellular components, including early endosome; endoplasmic reticulum; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.385C>T (p.R129C) alteration is located in exon 4 (coding exon 4) of the MGRN1 gene. This alteration results from a C to T substitution at nucleotide position 385, causing the arginine (R) at amino acid position 129 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
