Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PVS1_Moderate BS2

The NM_005357.4(LIPE):​c.3203_3221dupTAGACGGGGGCTGCGGGGG​(p.His1076ArgfsTer21) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00015 in 1,480,228 control chromosomes in the GnomAD database, including 2 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

LIPE (HGNC:6621): (lipase E, hormone sensitive type) The protein encoded by this gene has a long and a short form, generated by use of alternative translational start codons. The long form is expressed in steroidogenic tissues such as testis, where it converts cholesteryl esters to free cholesterol for steroid hormone production. The short form is expressed in adipose tissue, among others, where it hydrolyzes stored triglycerides to free fatty acids. [provided by RefSeq, Jul 2008]

LIPE-AS1 (HGNC:48589): (LIPE antisense RNA 1)

LOC101930071 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0031 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• BS2: High Homozygotes in GnomAdExome4 at 2 AR gene
