The NM_001034954.3(SORBS1):c.3307G>A(p.Val1103Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000502 in 1,614,060 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
SORBS1 (HGNC:14565): (sorbin and SH3 domain containing 1) This gene encodes a CBL-associated protein which functions in the signaling and stimulation of insulin. Mutations in this gene may be associated with human disorders of insulin resistance. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

The c.3307G>A (p.V1103I) alteration is located in exon 28 (coding exon 28) of the SORBS1 gene. This alteration results from a G to A substitution at nucleotide position 3307, causing the valine (V) at amino acid position 1103 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
