Genes affected

TTLL5 (HGNC:19963): (tubulin tyrosine ligase like 5) This gene encodes a member of the tubulin tyrosine ligase like protein family. This protein interacts with two glucocorticoid receptor coactivators, transcriptional intermediary factor 2 and steroid receptor coactivator 1. This protein may function as a coregulator of glucocorticoid receptor mediated gene induction and repression. This protein may also function as an alpha tubulin polyglutamylase.[provided by RefSeq, Feb 2010]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 139514). This premature translational stop signal has been observed in individual(s) with retinal dystrophy (PMID: 24791901). This variant is present in population databases (rs587777470, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Leu134Argfs*45) in the TTLL5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TTLL5 are known to be pathogenic (PMID: 24791901, 27162334). -
