Genes affected

STYK1 (HGNC:18889): (serine/threonine/tyrosine kinase 1) Receptor protein tyrosine kinases, like STYK1, play important roles in diverse cellular and developmental processes, such as cell proliferation, differentiation, and survival (Liu et al., 2004 [PubMed 15150103]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.844

The c.721T>C (p.F241L) alteration is located in exon 8 (coding exon 6) of the STYK1 gene. This alteration results from a T to C substitution at nucleotide position 721, causing the phenylalanine (F) at amino acid position 241 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
