Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.179G>A (p.S60N) alteration is located in exon 1 (coding exon 1) of the SPCS1 gene. This alteration results from a G to A substitution at nucleotide position 179, causing the serine (S) at amino acid position 60 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
