Genes affected
SPX (HGNC:28139): (spexin hormone) The protein encoded by this gene is a hormone involved in modulation of cardiovascular and renal function. It has also been shown in rats to cause weight loss. Several transcript variants have been found for this gene. [provided by RefSeq, Feb 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.95T>C (p.L32S) alteration is located in exon 3 (coding exon 3) of the SPX gene. This alteration results from a T to C substitution at nucleotide position 95, causing the leucine (L) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
