Genes affected

SALL2 (HGNC:10526): (spalt like transcription factor 2) This gene encodes a protein containing multiple zinc finger domains. The encoded protein functions in optical fissure closure during development of the eye in the embryo. Mutations in this gene are associated with ocular coloboma. [provided by RefSeq, Jul 2016]

The c.2854C>T (p.R952W) alteration is located in exon 2 (coding exon 2) of the SALL2 gene. This alteration results from a C to T substitution at nucleotide position 2854, causing the arginine (R) at amino acid position 952 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
