Genes affected
MDP1 (HGNC:28781): (magnesium dependent phosphatase 1) Predicted to enable acid phosphatase activity. Predicted to be involved in fructosamine metabolic process and peptidyl-tyrosine dephosphorylation. [provided by Alliance of Genome Resources, Apr 2022]
NEDD8-MDP1 (HGNC:39551): (NEDD8-MDP1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring NEDD8 (neural precursor cell expressed, developmentally down-regulated 8) and MDP1 (magnesium-dependent phosphatase 1) genes on chromosome 14. One of the read-through transcripts on this locus encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Jul 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 09, 2023The c.431G>A (p.G144E) alteration is located in exon 6 (coding exon 6) of the MDP1 gene. This alteration results from a G to A substitution at nucleotide position 431, causing the glycine (G) at amino acid position 144 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
