Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.299G>C (p.S100T) alteration is located in exon 3 (coding exon 3) of the PRRC2B gene. This alteration results from a G to C substitution at nucleotide position 299, causing the serine (S) at amino acid position 100 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
