Genes affected

GPR135 (HGNC:19991): (G protein-coupled receptor 135) Enables arrestin family protein binding activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Located in endosome and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

GPR135 links:

L3HYPDH (HGNC:20488): (trans-L-3-hydroxyproline dehydratase) The protein encoded by this gene is a dehydratase that converts trans-3-hydroxy-L-proline to delta(1)-pyrroline-2-carboxylate. This enzyme may function to degrade dietary proteins that contain trans-3-hydroxy-L-proline as well as other proteins such as collagen IV. The encoded protein can be converted to an epimerase by changing a threonine to a cysteine at a catalytic site. [provided by RefSeq, Sep 2016]

Ambry Genetics

Sep 28, 2022

The c.1028G>T (p.C343F) alteration is located in exon 1 (coding exon 1) of the GPR135 gene. This alteration results from a G to T substitution at nucleotide position 1028, causing the cysteine (C) at amino acid position 343 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
