Genes affected

TFPT (HGNC:13630): (TCF3 fusion partner) Predicted to enable DNA binding activity and protein kinase binding activity. Involved in apoptotic signaling pathway. Located in nucleoplasm. Part of Ino80 complex. [provided by Alliance of Genome Resources, Apr 2022]

PRPF31 (HGNC:15446): (pre-mRNA processing factor 31) This gene encodes a component of the spliceosome complex and is one of several retinitis pigmentosa-causing genes. When the gene product is added to the spliceosome complex, activation occurs.[provided by RefSeq, Jan 2009]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BP6: Variant 19-54115619-C-A is Benign according to our data. Variant chr19-54115619-C-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 330087.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS2: High Homozygotes in GnomAd at 2 AR gene
