Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.44G>T (p.G15V) alteration is located in exon 1 (coding exon 1) of the SWSAP1 gene. This alteration results from a G to T substitution at nucleotide position 44, causing the glycine (G) at amino acid position 15 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
