Genes affected

JKAMP (HGNC:20184): (JNK1/MAPK8 associated membrane protein) Enables ubiquitin protein ligase binding activity. Involved in ubiquitin-dependent ERAD pathway. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

JKAMP 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

May 09, 2022

The c.166T>A (p.Y56N) alteration is located in exon 3 (coding exon 3) of the JKAMP gene. This alteration results from a T to A substitution at nucleotide position 166, causing the tyrosine (Y) at amino acid position 56 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
