Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_024702.3(ZNF750):c.2017A>G(p.Met673Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000115 in 1,614,238 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M673K) has been classified as Likely benign.

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

Feb 27, 2023

The c.2017A>G (p.M673V) 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 2017, causing the methionine (M) at amino acid position 673 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
