Genetic Variant ZNF446:p.Gly340Arg (chr19-58480391-G-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_017908.4(ZNF446):c.1018G>C(p.Gly340Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000041 in 1,611,688 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. G340A) has been classified as Uncertain significance.

Genes affected

ZNF446 (HGNC:21036): (zinc finger protein 446) Enables identical protein binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Located in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

ZNF446 links:

SLC27A5 (HGNC:10999): (solute carrier family 27 member 5) The protein encoded by this gene is an isozyme of very long-chain acyl-CoA synthetase (VLCS). It is capable of activating very long-chain fatty-acids containing 24- and 26-carbons. It is expressed in liver and associated with endoplasmic reticulum but not with peroxisomes. Its primary role is in fatty acid elongation or complex lipid synthesis rather than in degradation. This gene has a mouse ortholog. [provided by RefSeq, Jul 2008]
