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 GeneticsJun 22, 2023The c.125G>A (p.G42D) alteration is located in exon 3 (coding exon 3) of the MDP1 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the glycine (G) at amino acid position 42 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
