Genes affected

SCAND1 (HGNC:10566): (SCAN domain containing 1) This gene encodes a SCAN box domain-containing protein. The SCAN domain is a highly conserved, leucine-rich motif of approximately 60 aa originally found within a subfamily of zinc finger proteins. This gene belongs to a family of genes that encode an isolated SCAN domain, but no zinc finger motif. This protein binds to and may regulate the function of the transcription factor myeloid zinc finger 1B. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jan 2011]

The c.413C>T (p.P138L) alteration is located in exon 2 (coding exon 2) of the SCAND1 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
