Variant chr14-59464286-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_022571.6(GPR135):c.941T>C(p.Val314Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000713 in 1,611,824 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V314M) has been classified as Uncertain significance.

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]

The c.941T>C (p.V314A) alteration is located in exon 1 (coding exon 1) of the GPR135 gene. This alteration results from a T to C substitution at nucleotide position 941, causing the valine (V) at amino acid position 314 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
