Genes affected

TMEM237 (HGNC:14432): (transmembrane protein 237) The protein encoded by this gene is a tetraspanin protein that is thought to be involved in WNT signaling. Defects in this gene are a cause of Joubert syndrome-14. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.88).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00025 (38/152294) while in subpopulation SAS AF = 0.00745 (36/4830). AF 95% confidence interval is 0.00553. There are 1 homozygotes in GnomAd4. There are 31 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
