Genes affected

DUSP18 (HGNC:18484): (dual specificity phosphatase 18) Dual-specificity phosphatases (DUSPs) constitute a large heterogeneous subgroup of the type I cysteine-based protein-tyrosine phosphatase superfamily. DUSPs are characterized by their ability to dephosphorylate both tyrosine and serine/threonine residues. They have been implicated as major modulators of critical signaling pathways. DUSP18 contains the consensus DUSP C-terminal catalytic domain but lacks the N-terminal CH2 domain found in the MKP (mitogen-activated protein kinase phosphatase) class of DUSPs (see MIM 600714) (summary by Patterson et al., 2009 [PubMed 19228121]).[supplied by OMIM, Dec 2009]

Ambry Genetics

Feb 10, 2022

The c.232C>T (p.R78C) alteration is located in exon 2 (coding exon 1) of the DUSP18 gene. This alteration results from a C to T substitution at nucleotide position 232, causing the arginine (R) at amino acid position 78 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
