Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.1907C>T (p.T636M) alteration is located in exon 8 (coding exon 5) of the DLGAP1 gene. This alteration results from a C to T substitution at nucleotide position 1907, causing the threonine (T) at amino acid position 636 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
