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 GeneticsFeb 06, 2024The c.481G>A (p.V161I) alteration is located in exon 5 (coding exon 5) of the MGRN1 gene. This alteration results from a G to A substitution at nucleotide position 481, causing the valine (V) at amino acid position 161 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
