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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.254C>A (p.S85Y) alteration is located in exon 4 (coding exon 4) of the JKAMP gene. This alteration results from a C to A substitution at nucleotide position 254, causing the serine (S) at amino acid position 85 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
