Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM2 PM5 PP3_Strong PP5_Moderate

The NM_022095.4(ZNF335):​c.3332G>T​(p.Arg1111Leu) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,878 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1111H) has been classified as Pathogenic.

Genes affected

ZNF335 (HGNC:15807): (zinc finger protein 335) The protein encoded by this gene enhances transcriptional activation by ligand-bound nuclear hormone receptors. However, it does this not by direct interaction with the receptor, but by direct interaction with the nuclear hormone receptor transcriptional coactivator NRC. The encoded protein may function by altering local chromatin structure. [provided by RefSeq, Jul 2008]

ZNF335 Gene-Disease associations (from GenCC):

• microcephalic primordial dwarfism due to ZNF335 deficiency

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr20-45950453-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 40116.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP3: Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 20-45950453-C-A is Pathogenic according to our data. Variant chr20-45950453-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 225017.Status of the report is criteria_provided_single_submitter, 1 stars.
