Genes affected
PKHD1 (HGNC:9016): (PKHD1 ciliary IPT domain containing fibrocystin/polyductin) The protein encoded by this gene is predicted to have a single transmembrane (TM)-spanning domain and multiple copies of an immunoglobulin-like plexin-transcription-factor domain. Alternative splicing results in two transcript variants encoding different isoforms. Other alternatively spliced transcripts have been described, but the full length sequences have not been determined. Several of these transcripts are predicted to encode truncated products which lack the TM and may be secreted. Mutations in this gene cause autosomal recessive polycystic kidney disease, also known as polycystic kidney and hepatic disease-1. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 3 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.85).
BP6
Variant 6-52026213-T-C is Benign according to our data. Variant chr6-52026213-T-C is described in CliVar as Benign. Clinvar id is 262399.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-52026213-T-C is described in CliVar as Benign. Clinvar id is 262399.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-52026213-T-C is described in CliVar as Benign. Clinvar id is 262399.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-52026213-T-C is described in CliVar as Benign. Clinvar id is 262399.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BA1
