Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.1722G>T (p.R574S) alteration is located in exon 4 (coding exon 4) of the SPTY2D1 gene. This alteration results from a G to T substitution at nucleotide position 1722, causing the arginine (R) at amino acid position 574 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
