Genes affected
HDAC4 (HGNC:14063): (histone deacetylase 4) Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. The protein encoded by this gene belongs to class II of the histone deacetylase/acuc/apha family. It possesses histone deacetylase activity and represses transcription when tethered to a promoter. This protein does not bind DNA directly, but through transcription factors MEF2C and MEF2D. It seems to interact in a multiprotein complex with RbAp48 and HDAC3. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HDAC4. . Gene score misZ 2.926 (greater than the threshold 3.09). Trascript score misZ 3.7504 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with central hypotonia and dysmorphic facies, 2q37 microdeletion syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.009914041).
BP6
Variant 2-239053470-C-T is Benign according to our data. Variant chr2-239053470-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 374654.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000433 (66/152342) while in subpopulation SAS AF= 0.000828 (4/4832). AF 95% confidence interval is 0.000431. There are 0 homozygotes in gnomad4. There are 35 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High AC in GnomAd4 at 66 AD gene.
