Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PHYKPL gene is commonly pathogenic or not. These statistics are base on transcript: NM_000153373.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Catalyzes the pyridoxal-phosphate-dependent breakdown of 5-phosphohydroxy-L-lysine, converting it to ammonia, inorganic phosphate and 2-aminoadipate semialdehyde. {ECO:0000269|PubMed:22241472}.
• Disease: DISEASE: Phosphohydroxylysinuria (PHLU) [MIM:615011]: A condition characterized by elevated phosphohydroxylysine in the urine. There is no clinical phenotype associated with this finding other than the urinary metabolites. {ECO:0000269|PubMed:23242558}. Note=The disease is caused by mutations affecting the gene represented in this entry.
