Genes affected

SALL4 (HGNC:15924): (spalt like transcription factor 4) This gene encodes a zinc finger transcription factor thought to play a role in the development of abducens motor neurons. Defects in this gene are a cause of Duane-radial ray syndrome (DRRS). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

The c.3098C>T (p.T1033I) alteration is located in exon 4 (coding exon 4) of the SALL4 gene. This alteration results from a C to T substitution at nucleotide position 3098, causing the threonine (T) at amino acid position 1033 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The SALL4 c.3098C>T variant is predicted to result in the amino acid substitution p.Thr1033Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0028% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
