Genes affected

ZNF750 (HGNC:25843): (zinc finger protein 750) This gene encodes a protein with a nuclear localization site and a C2H2 zinc finger domain. Mutations in this gene have been associated with seborrhea-like dermatitis with psoriasiform elements. [provided by RefSeq, Jul 2008]

ZNF750 links:

TBCD (HGNC:11581): (tubulin folding cofactor D) Cofactor D is one of four proteins (cofactors A, D, E, and C) involved in the pathway leading to correctly folded beta-tubulin from folding intermediates. Cofactors A and D are believed to play a role in capturing and stabilizing beta-tubulin intermediates in a quasi-native confirmation. Cofactor E binds to the cofactor D/beta-tubulin complex; interaction with cofactor C then causes the release of beta-tubulin polypeptides that are committed to the native state.

Ambry Genetics

Nov 03, 2023

The c.1931A>G (p.Y644C) alteration is located in exon 3 (coding exon 2) of the ZNF750 gene. This alteration results from a A to G substitution at nucleotide position 1931, causing the tyrosine (Y) at amino acid position 644 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
