not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.1031C>T (p.T344M) alteration is located in exon 10 (coding exon 10) of the HSDL2 gene. This alteration results from a C to T substitution at nucleotide position 1031, causing the threonine (T) at amino acid position 344 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
