Genes affected

KHDRBS1 (HGNC:18116): (KH RNA binding domain containing, signal transduction associated 1) This gene encodes a member of the K homology domain-containing, RNA-binding, signal transduction-associated protein family. The encoded protein appears to have many functions and may be involved in a variety of cellular processes, including alternative splicing, cell cycle regulation, RNA 3'-end formation, tumorigenesis, and regulation of human immunodeficiency virus gene expression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.1430259).

Collection Method: clinical testing

The c.902C>A (p.P301H) alteration is located in exon 5 (coding exon 5) of the KHDRBS1 gene. This alteration results from a C to A substitution at nucleotide position 902, causing the proline (P) at amino acid position 301 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
