Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.2249C>T (p.S750L) alteration is located in exon 13 (coding exon 13) of the TMEM8A gene. This alteration results from a C to T substitution at nucleotide position 2249, causing the serine (S) at amino acid position 750 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
