Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.418T>C (p.C140R) alteration is located in exon 4 (coding exon 4) of the PGS1 gene. This alteration results from a T to C substitution at nucleotide position 418, causing the cysteine (C) at amino acid position 140 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
