Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.643G>A (p.A215T) alteration is located in exon 4 (coding exon 3) of the SYNDIG1L gene. This alteration results from a G to A substitution at nucleotide position 643, causing the alanine (A) at amino acid position 215 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
