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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.719C>T (p.P240L) alteration is located in exon 6 (coding exon 5) of the ZNF446 gene. This alteration results from a C to T substitution at nucleotide position 719, causing the proline (P) at amino acid position 240 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
