Genes affected
SCYL2 (HGNC:19286): (SCY1 like pseudokinase 2) The protein encoded by this gene associates with clathrin-coated complexes at the plasma membrane and with endocytic coated vesicles. The encoded protein phosphorylates the beta2 subunit of the plasma membrane adapter complex AP2 and interacts with clathrin, showing involvement in clathrin-dependent pathways between the trans-Golgi network and the endosomal system. In addition, this protein has a role in the Wnt signaling pathway by targeting frizzled 5 (Fzd5) for lysosomal degradation. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Dec 2015]

The c.624A>T (p.E208D) alteration is located in exon 5 (coding exon 4) of the SCYL2 gene. This alteration results from a A to T substitution at nucleotide position 624, causing the glutamic acid (E) at amino acid position 208 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
