Genetic Variant PLIN4:p.Ser1333Asn (chr19-4504577-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001367868.2(PLIN4):c.3998G>A(p.Ser1333Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000269 in 1,601,294 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. S1333R) has been classified as Uncertain significance.

The c.3956G>A (p.S1319N) alteration is located in exon 6 (coding exon 6) of the PLIN4 gene. This alteration results from a G to A substitution at nucleotide position 3956, causing the serine (S) at amino acid position 1319 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
