Genes affected

LPAR6 (HGNC:15520): (lysophosphatidic acid receptor 6) The protein encoded by this gene belongs to the family of G-protein coupled receptors, that are preferentially activated by adenosine and uridine nucleotides. This gene aligns with an internal intron of the retinoblastoma susceptibility gene in the reverse orientation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2009]

LPAR6 links:

RB1 (HGNC:9884): (RB transcriptional corepressor 1) The protein encoded by this gene is a negative regulator of the cell cycle and was the first tumor suppressor gene found. The encoded protein also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in this gene are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma. [provided by RefSeq, Jul 2008]

3billion

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.001%). Predicted Consequence/Location: Missense variant Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000001828 /PMID: 18461368 /3billion dataset). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 21426374, 31077348). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: curation

This variant is interpreted as likely pathogenic for Hypotrichosis 8, autosomal recessive. The following ACMG Tag(s) were applied: Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium (PM2); Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PP1 upgraded to moderate); For recessive disorders, detected in trans with a pathogenic variant (PM3); Well-established functional studies show a deleterious effect (PS3 downgraded to supporting) -

Significance: Likely pathogenic

Review Status: no assertion criteria provided

Collection Method: clinical testing

Our laboratory reported dual molecular diagnoses in AGL (NM_000028.2, c.3836+1G>A) and LPAR6 (NM_005767.4, c.436G>A) in an individual with reported features of motor and speech delay, seizure disorder, woolly sparse hair and eye brows, and massive hepatomegaly. Thie LPAR6 VUS has been previously reported, but there is not sufficient information to categorize it as disease-causing. -
