Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP3BS2

The NM_004650.3(PNPLA4):c.251G>A(p.Gly84Asp) variant causes a missense change. The variant allele was found at a frequency of 0.000119 in 1,206,143 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 46 hemizygotes in GnomAD. In-silico tool predicts a pathogenic 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. G84S) has been classified as Uncertain significance.

Genes affected

PNPLA4 (HGNC:24887): (patatin like phospholipase domain containing 4) This gene encodes a member of the patatin-like family of phospholipases. The encoded enzyme has both triacylglycerol lipase and transacylase activities and may be involved in adipocyte triglyceride homeostasis. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome Y. [provided by RefSeq, Feb 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.251G>A (p.G84D) alteration is located in exon 3 (coding exon 2) of the PNPLA4 gene. This alteration results from a G to A substitution at nucleotide position 251, causing the glycine (G) at amino acid position 84 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
