Genes affected

PHYKPL (HGNC:28249): (5-phosphohydroxy-L-lysine phospho-lyase) This is a nuclear gene encoding a mitochondrial enzyme that catalyzes the conversion of 5-phosphonooxy-L-lysine to ammonia, inorganic phosphate, and 2-aminoadipate semialdehyde. Mutations in this gene may cause phosphohydroxylysinuria. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

Collection Method: clinical testing

The c.1233T>A (p.F411L) alteration is located in exon 11 (coding exon 11) of the PHYKPL gene. This alteration results from a T to A substitution at nucleotide position 1233, causing the phenylalanine (F) at amino acid position 411 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
