What condition is associated with NPHP4 c.810+8del?

NPHP4 c.810+8del is associated with nephronophthisis (ClinVar).

How common is NPHP4 c.810+8del in the general population?

NPHP4 c.810+8del is very rare (popmax 0.00141%, afr) (gnomAD).

How is Nephronophthisis inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
