Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Foundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human Genetics	Apr 21, 2023	A heterozygous missense variation in exon 11 of the PMFBP1 gene that results in premature stop codon was detected.. The observed variant c.1462C>T(p.Gln488Ter) not observed in the 1000Genomes database and have MAF of 0.0003% in the gnomAD database. The in silico prediction of the variant is damaging by BayesDEL. The reference codon is conserved across species. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. The observed variant was validated in mother and father using sanger sequencing. The variant was detected in heterozygous state in father, whereas was wildtype in mother. -
