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]

The c.485C>G (p.T162S) alteration is located in exon 6 (coding exon 6) of the MDP1 gene. This alteration results from a C to G substitution at nucleotide position 485, causing the threonine (T) at amino acid position 162 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
