Variant names:

• chr17-74371783-C-A
• rs1485335558
• NM_001331076.1:c.308C>A

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001331076.1(GPR142):​c.308C>A​(p.Pro103His) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P103L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
