Genes affected

THAP5 (HGNC:23188): (THAP domain containing 5) Enables protease binding activity. Involved in negative regulation of cell cycle and negative regulation of transcription by RNA polymerase II. Located in chromatin and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

PNPLA8 (HGNC:28900): (patatin like phospholipase domain containing 8) This gene encodes a member of the patatin-like phospholipase domain containing protein family. Members of this family are phospholipases which catalyze the cleavage of fatty acids from membrane phospholipids. The product of this gene is a calcium-independent phospholipase. Mutations in this gene have been associated with mitochondrial myopathy with lactic acidosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2015]

PNPLA8 Gene-Disease associations (from GenCC):

• mitochondrial myopathy-lactic acidosis-deafness syndrome

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.335 is higher than 0.05.
